解説
この第107首「天かけり光の神は降りたちぬかがやきわたる海の底にも。」は、第106首で「天照るの吾れ」として“自分のうちの光”を歌ったあと、その光の源としての「光の神」の働きを宇宙スケールの縦軸で描き直している感じがします。ページの注が示すように、「天かけり（天翔り）」は高天原から人の世へと駆ける神の運動を呼び込む古い言い回しで、「降り立ちぬ」の「ぬ」は完了の助動詞として「まさしく降り立ったのだ」を強く言い切る用法。続く「かがやきわたる海の底にも」の「わたる」で、光が一点ではなく空間全体に行きわたるニュアンスを出し、「にも」の“も”が「海の底ですら」という“垂直のふり幅”を強調する、と解説されています。つまりこの首は、天上から海の最深部にいたるまで、光の神が実際に降り立ち、その輝きが届いている世界像を一息で言い切っているわけです。
植芝盛平の六つのプライマーの糸をここに戻すと、「光の神」はプライマーの第一原理〈武＝宇宙原理〉とプライマーの第六原理〈「至愛」の源に順う〉を合わせたような存在として読めます。プライマーの第四原理〈和合美化〉で見た“世界を美へ向けて整える力”が、ここでは光としての合気＝万和合の力（第105首）に姿を変え、天から“降り立ち”つつ、目に見える世界だけでなく、海の底のような「隠れた領域」まで満たしていく。プライマーの第三原理〈心魂一如〉に照らせば、この光は外側の宇宙だけでなく、私たち自身の心の深海（トラウマや怒り、見たくない部分）にまで届いてこそ本当だ、とも読めるし、プライマーの第二原理〈神や人との合気〉の観点では、対神や人関係の「底」に沈んだもの――恨みや誤解――にまで、静かに光を届かせる働きとして味わうこともできます。プライマーの第五原理〈体＝道場、心＝修業者／修行者心／学び手〉に戻せば、自分のからだ全体を“光の降り立つ中継点”として磨くことが、日々の稽古の目盛りになる、ということでもあります。
直前の三首ともきれいに連なります。第104首は「合気とは解けばむつかし道なれどありのままなる天のめぐりに」と、合気を“ありのままの天のめぐり”とし、第105首は「万和合の力なりたゆまず磨け道の人々」と、そのめぐりを起こす力が万物の和合だと定義しました。第106首はその天の光を、自分の身と心にまで引き寄せて「朝日さす心もさえて…天照るの吾れ」と歌い、自分自身が“天照る者”として立ち上がる瞬間を描いていました。その流れの上で第107首は、その“天照る光”の本体である「光の神」が天を駆け、地上に降り立ち、その輝きが海の底の底までしみわたっているという、合気＝宇宙原理の働きをマクロな一枚絵として見せてくれる首だと言えるでしょう。私たちの稽古が、本当に 第105首 のいう“万和合”に向かっているかどうかは――この光が、自分の内側と、出会う人びとの「深いところ」にまで届きはじめているかでこそ測れるのだ、とこのページは示唆しているように思えます。
補説――光の降下と遍照をかたちにする歌法
この首で、まだ明示されていない歌法としてまず目につくのは、初句と結句を向かい合わせた首尾照応です。第一句の「天」と第五句の「海の底」が歌の最上部と最下部を受け持ち、第二句の「光の神」と第四句の「かがやき」が、光の主体とその働きとして照応する。そのあいだに第三句の「降りたちぬ」が置かれているので、五句全体が〈場所――光――降臨――光――場所〉という鏡のような折り返しをつくっています。「天」と「底」は同じものを反復するのではなく、宇宙の両極を対照させることによって互いを照らし出す、首尾照応を伴った対照法になっているわけです。
しかも三十一音を数えてみると、一首の正中にあたる第十六音は「降りたちぬ」の「ち」で、「立ち」という語がちょうど詩型の中心をまたいでいます。意図を断定する必要はないにせよ、神が降って「立つ」その語が、一首の腰に実際に立っているという配置はかなり美しいところです。五句を縦に分かち書きして見れば、最上段の「天」から、中段の「降り」を経て、最下段の「底」へ視線そのものが下っていく。内容が降臨を語るだけでなく、文字を読む運動までが降臨を演じており、詩型そのものが一種の垂直な見立てになっている感じがします。
動詞の組み方にも、光の運動を止めない仕掛けがあります。「天翔り」は連用形のまま次句へ開かれ、「光の神は」を受けて「降り立ちぬ」へ至る。「降り立つ」の内部にも「降り」と「立ち」という二つの運動が畳み込まれ、さらに下の句では「輝き」に「渡る」が接続されます。つまり、天を翔る運動、上から下へ降る運動、ある一点に立つ運動、そこから全域へ渡っていく運動が、動詞の連鎖として順に展開されているわけです。「天翔り」が天空を横切り、「降り立ちぬ」が垂直軸をつくり、「かがやきわたる」がその光を面から奥行きへまで拡張するので、単なる上下運動ではなく、空間全体を三次元的に満たしていく構図になっています。
ここでは第三句の完了の助動詞「ぬ」と、第四句の「わたる」との対照も大切です。「降り立ちぬ」は一回の決定的な出来事を、すでに成就したものとして閉じる。それに対して「かがやきわたる」は、その結果として生じた光が、なお広がりつづけている状態を開いていく。上の句では降臨が完了し、下の句ではその作用が終わらずに持続するという、完了相と持続・遍在相との対照です。第四句の七音すべてを「かがやきわたる」という一つの複合動詞が占めていることも見逃せません。「行きわたる」という意味の語が、文字どおり七音の一句全体へ行きわたっており、ここでも内容と形式とが重なっています。
各句は定型どおりに収まっていますが、意味と統語は句境でいちいち停止しません。「天かけり」だけでは文が閉じず、「光の神は」を経て「降りたちぬ」まで読まなければ運動の主体と帰着が定まらない。同じように「かがやきわたる」は、第五句の「海の底にも」が加わって初めて、その到達範囲を明らかにします。一語そのものを五音・七音の境で割る狭義の句跨りではありませんが、文意が句境を越えて受け渡される、統語上の句跨りと見ることができます。光が天・地・海という領域の境を越えるように、文もまた五・七・五・七・七の境界を越えて流れていくわけです。
第四・五句には、さらに倒置法が働いています。通常の語順なら「海の底にも、かがやきわたる」となるところを、「かがやきわたる／海の底にも」と述語を先に置き、到達点を最後まで遅らせている。これによって第四句ではまず光の拡張そのものが立ち上がり、結句に来て初めて、その光が届いた極限地点として「海の底」が現れます。読み手の視線は、輝きの動きに引かれたあと、最後の七音で一気に深みへ沈められることになります。
また「わたる」は、終止形と連体形が同じ形であるため、第四句には統語的な揺れも生まれます。独立した述語として聞けば、「光がかがやきわたる――海の底にも」という倒置になる。一方、連体形として聞けば、「かがやきわたる海」というまとまりが一瞬立ち上がり、海そのものまで発光する世界像が前へ出てきます。これは同音異義語を重ねる教科書的な掛詞ではありませんが、終止と連体の二つの働きが同じ音形に重なる、文法上の「掛け」に近い効果です。光が海へ届くという読みと、海そのものが光の場へ変わったという読みとが、完全には分離されずに残されている感じがします。
結句の「海の底にも」は、厳密には体言止めではありません。「海の底」という体言のあとに、格助詞「に」と係助詞「も」が続いているので、より正確には「にも」による助詞止め、あるいは前に置かれた述語を心のなかで補わせる省略表現です。この「も」は、「海の底でさえ」という極限の一点を示すと同時に、そこまで届くのであれば、その手前にあるすべての場所にも届いているはずだ、という全体を言外に包み込みます。歌は「届いた」「照らした」ともう一度言い切らず、「海の底にも」で止まる。そのため、光は結句で閉じ込められず、歌の外側へなお行きわたっていく余韻を残します。
第二句末の「は」と結句末の「も」との照応も、ひそかな骨組みになっています。「光の神は」の「は」は神を一首の話題として立て、「海の底にも」の「も」は、その神の作用へ最も遠い領域まで加えていく。「は」が一つの主体を取り立てるのに対し、「も」はその作用域を包摂的に広げるので、歌の文法は〈神を立てること〉から〈何ものも光の外へ置かないこと〉へ移っていきます。ただし、これは「ぞ・なむ・や・か・こそ」のように結びの活用形を変える正式な係り結びではありません。係り結びではなく、二つの係助詞が一首の前半と末尾で呼び交わす、助詞の照応として見るのがよいでしょう。
音の面では、「天かけり」の「かけり」、「光」の「ひかり」、「降り」の「おり」と、上の句を通して「り」の音が繰り返されます。さらに「かけり」「ひかり」「かみ」「かがやき」には「か」の音が連鎖しており、意味の上で光が移動すると同時に、光を示す音も第一句から第四句へ受け渡されていく。「光」と「かがやき」は明るさの縁語であり、「翔り・降り・立ち・渡る」は運動の縁語、「天・海・底」は空間の縁語としてまとまっています。異なる語を次々に置きながら、意味の場を途切れさせない縁語群が、この首の一息で流れる感じを支えているわけです。
とくに「わたる」には、「一面に及ぶ」という補助動詞的な意味だけでなく、本来の「こちらから向こうへ渡る」という移動の意味も残っています。その直後に「海」が置かれるため、「輝きが全域に及ぶ」という読みの背後で、「光が海を渡る」という具体的な像までうっすら動き出す。これも厳密な掛詞とは言い切れませんが、一つの語の複数の意味を隣接語によって同時に活性化させる、掛詞的な多義性と呼べるでしょう。「天」の音に海女の「あま」が遠く響くのと同じように、「渡る」の語義にも海の側から光が当て返されています。
母音の響きにも、小さな転調があります。「かがやきわたる」では「あ」の開いた音が大きく連なり、光が外へ広がるような明るい響きをつくる。それが「うみのそこにも」へ入ると、「う・お」の丸く深い音が増え、声の響きまで海底へ沈んでいくように聞こえます。もちろん母音だけから作者の意図を断定することはできませんが、第四句の拡張する音色と、第五句の沈み込む音色との対照は、声に出したときにとくにはっきり現れます。視線だけでなく、発声の響きまでが、輝きから深みへの運動をなぞっているわけです。
「光の神」という表現も、単なる擬人法として片づけるより、二段階の喩法として見るとおもしろいところです。まず抽象的な「光」が、翔り、降り、立つことのできる神的主体へと神格化される。ところが下の句へ入ると、その神は名を反復されず、「かがやき」という作用へ姿を変えて世界へ溶け出していきます。神そのものを、その属性であり働きでもある輝きによって示す換喩です。上の句では光が神として一つの姿を取り、下の句では神が再び光へほどけて万物へ行きわたる。この〈神格化――降臨――換喩的拡散〉の流れが、第106首の「天照るの吾れ」から、第107首の遍照する宇宙へ視野を開く働きをしているように思えます。
したがって、この首は固定した枕詞や特定の歌枕、本歌取り、明示的な係り結び、あるいは体言止めによって技巧を前へ出す歌ではありません。「天かけり」を序詞的・枕詞的な導入として聞くことはできますが、古典的な固定枕詞と断定するより、連用形の開きと神話的な歌語の働きを見る方が自然でしょう。この一首の力はむしろ、首尾の対照、正中に置かれた「立ち」、動詞の連鎖、完了から持続への相の転換、倒置と助詞止め、音韻と縁語の照応といった仕掛けが一つになり、三十一音そのものを「天から海の底まで光が通る道」に変えているところにあります。
文法上は、「海の底にも」を体言止めではなく助詞止め／倒置・省略として扱い、「は」「も」を正式な係り結びではなく係助詞の照応として扱うのが精確です。文の切れ目・倒置・連体止め・省略を組み合わせて和歌を読む方法は、国語学でも一つのまとまった分析枠として扱われています。また和歌の倒置には、最後に送られた語句を強く印象づける働きがあります。 「は」と「も」は係助詞に分類されますが、「ぞ・なむ・や・か・こそ」のように結びの活用形を変化させる係り結びは起こしません。
口語要約のひとこと
「天をかける光の神が地上へ降り立ち、その輝きは海のいちばん底にまで行きわたっている。」
発話行為理論
この首をオースティン（Austin, 1962）の発話行為論で見てみると、まず発話行為（locutionary）として言われているのは、天を翔ける「光の神」がすでに「降り立ち」、その輝きが「海の底にも」及んでいる、という宇宙的事態です。ただし大事なのは、意味内容だけでなく、言い方の組み方そのものが意味を担っていることです。上の句と下の句の折りでは、第一・二句の「天かけり／光の神は」が第四句の「かがやきわたる」へ折り返され、名として置かれた神が、はたらきとしての光へ開いていく。さらに第三句の「降りたちぬ」が、第五句の「海の底にも」によって終点を与えられるので、天上の運動と海底の到達とが、一つの文脈のなかへきれいに畳み込まれているわけです。
つぎに発話内行為（illocutionary）として読むと、この首がしているのは、出来事の記述だけではなく、その降臨を言い立て、光が全域に及んでいる世界像を宣言することだと見えてきます。とくに第三句の「降りたちぬ」は、強い切れをつくる要で、ここでいったん降臨が完了したものとして言い切られ、そのあとで第四・五句が到達範囲を開いていく。しかも「あま」の音には、天と、海の側へひそかに響く気配とが重なっていて、厳密な教科書的掛詞とまでは言い切らなくても、上下の世界を先取りでつないでしまう音の橋がかかっている感じがします。
最後に発話媒介行為（perlocutionary）としては、読みの場に生まれるのは、畏れや慰めだけでなく、「底」に沈んだものまで照らされうるという感覚の変化でしょう。海の底は、遠い場所の比喩にとどまらず、稽古のなかでまだ光の届いていない層、ことばにならない痛みや濁りの層まで含んで響きだします。そう受けとると、この首のはたらきは宇宙論の説明で終わらず、見えにくい深みへまで合気の光を通していくべきだという、静かな方向づけとして立ち上がってくる感じがします。
コーダ
この首の終わりに残るのは、光の華やかさよりも、「どこに立つのか」という問いなのかもしれません。「天かけり」と翔った神は、ただ「降り」るのではなく、「立ち」ます。しかも、その「立ち」という語は、三十一音の正中をまたぐように置かれている。光は遠い天上の理念のままではなく、身体と世界のある一点に足場を得てはじめて、そこから「かがやきわたる」働きとなります。合気という宇宙原理も、説明され、理解されたというだけでは、まだ稽古の場へ降臨したことにはならない。呼吸、姿勢、間合い、触れ方、そして他者への応答のうちに立ったとき、はじめて現実の働きとなるのでしょう。
だから、「海の底にも」の「も」は、単なる宇宙的な誇張ではありません。目に見えるところ、整ったところ、説明できるところだけを照らして満足してはならないという、静かな試金石です。自分の痛み、怒り、羞恥、恐れ、関係の底に沈んだ恨みや誤解――そうしたものは、光によって消し去られるというより、もはや光の外へ追いやられなくなる。遍照とは暗さを否認することではなく、その暗ささえも関係のなかへ戻し、和合美化の働きが届きうる場所として受け取り直すことなのでしょう。
ここでは、六つのプライマーも、「降り立つ」という動詞と「にも」という助詞へ凝縮されているように見えます。宇宙原理と至愛の源は天上にとどまらず、身体という道場へ降り立つ。心魂一如として内なる深みに通り、人との合気として他者とのあいだへ及び、和合美化として、これまで切り離されていたものまで一つの世界へ結び戻していく。「立つ」は原理が身体を得る瞬間であり、「も」は何ものもその働きの外へ置かないという広がりです。
そして、「降りたちぬ」の完了と「かがやきわたる」の持続は、修行の二つの時を示しています。源の側から見れば、光はすでに降り立っている。しかし修行者の側から見れば、その光を身体の隅々、心魂の深み、他者とのあいだへ通していく仕事は、なお終わっていない。私たちは光を所有するのではなく、その通り道となる。身体を道場として磨くとは、この「すでに」と「なお」のあいだに立ちつづけることなのかもしれません。
一首を閉じる「にも」は、それゆえ結論というより開口部です。海の底にまで届くのであれば、その途中にあるものは何一つ光の外にはない。天、地、身体、心、他者、そしてまだ言葉にならない深みまでが、一つの縦軸に結ばれていく。第107首が差し出すのは、上を仰いで光の到来を待つ姿ではありません。すでに降り立った光が、自分を通ってどこまで届くのかを問われる姿です。合気とは、その問いに技だけで答えるのではなく、生き方の全体をもって答えつづけることなのかもしれません。

Commentary
Dōka 107, ama kakeri hikari no kami wa oritachinu kagayaki wataru umi no soko ni mo (天かけり光の神は降りたちぬかがやきわたる海の底にも), seems to redraw, along a cosmic vertical axis, the activity of the “kami of light” (and “light’s kami”) as the source of the inward light sung in Dōka 106 through the phrase amateru no ware (天照るの吾れ), “I, shining as heaven.” As the notes on the page indicate, ama kakeri (天かけり; 天翔り), “coursing through heaven,” is an old expression that summons the movement of kami racing from Takamagahara (高天原), the Plain of High Heaven, into the human world. The nu (ぬ) in oritachinu (降り立ちぬ) is the auxiliary of completion, used here to state emphatically that the deity “has indeed descended and taken their stand.” The following wataru (わたる), in kagayaki wataru umi no soko ni mo (かがやきわたる海の底にも), gives the sense that the light does not remain concentrated at a single point but extends throughout the whole of space, while the particle mo (も) in ni mo (にも) emphasizes the full vertical span: “even at the bottom of the sea.” In other words, the poem declares in a single breath a vision of the world in which the god of light has actually descended and taken his stand, and in which that radiance reaches from the heavens to the deepest part of the sea.
Drawing the threads of Ueshiba Morihei’s Six Primers back into this poem, the “kami of light” may be read as a presence combining the First Principle, Bu = Uchū Genri (武＝宇宙原理), “Bu = Cosmic Principle,” with the Sixth Principle, Shiai no Minamoto ni Shitagau (「至愛」の源に順う), “accord with the source of Supreme Love.” The “power that orders the world toward beauty,” encountered in the Fourth Principle, Wagō Bika (和合美化), “Harmonization and Beautification,” here changes form into light: aiki as the power of universal harmonization described in Dōka 105. Descending from heaven, it fills not only the visible world but also “hidden regions” like the bottom of the sea. Viewed in the light of the Third Principle, Shinkon Ichinyo (心魂一如), “Heart-mind and Spirit, Inseparable,” this radiance is genuine only if it reaches not merely the outer cosmos but also the deep sea within the heart-mind—trauma, anger, and those regions one would rather not see. From the perspective of the Second Principle, Kami ya Hito to no Aiki (神や人との合気), “Aiki with Kami / Another / Others,” it may also be savored as the quiet work of bringing light even to what has sunk to the “bottom” of a kami and human relationships: resentment, misunderstanding, and what has remained unspoken. Returning to the Fifth Principle, Karada/Tai = Dōjō, Kokoro = Shugyōsha, Shugyōsha, Manabite (体＝道場、心＝修業者／修行者／学び手), “Body = Dōjō; Heart-mind = Practitioner, Ascetic, Learner,” the measure of daily training becomes the polishing of the entire body into a relay point at which this light may descend and take its stand.
The poem also follows beautifully from the three immediately preceding it. Dōka 104, aiki to wa tokeba mutsukashi michi naredo ari no mama naru ame no meguri ni (合気とは解けばむつかし道なれどありのままなる天のめぐりに), presents aiki as “the turning of heaven just as it is.” Dōka 105, ban-wagō no chikara nari tayumazu migake michi no hitobito (万和合の力なりたゆまず磨け道の人々), defines the power that brings about this turning as the universal harmonization of all things. Dōka 106 then draws that heavenly light all the way into one’s own body and heart-mind through asahi sasu kokoro mo saete … amateru no ware (朝日さす心もさえて……天照るの吾れ), depicting the moment in which the self rises as an amateru mono (天照る者), “one who shines as heaven.” Following that movement, Dōka 107 presents the “kami of light,” the very body of that heavenly radiance, coursing through the heavens, descending to earth, and suffusing even the deepest bottom of the sea. It offers, as a single macroscopic image, the activity of aiki as Cosmic Principle. The page seems to suggest that the degree to which training is truly moving toward the Ban-Wagō (万和合), “Universal Harmonization,” of Dōka 105 can be measured precisely by whether this light has begun to reach the deeper places within oneself and within the people one encounters.
Supplementary note: Poetic forms that give shape to the descent and pervasive illumination
Among the poetic devices not yet made explicit in this poem, the first to stand out is shubi shōō (首尾照応), the correspondence between beginning and end. The ama (天), “heaven,” of the first line and umi no soko (海の底), “the bottom of the sea,” in the fifth assume responsibility for the poem’s uppermost and lowermost points. The hikari no kami (光の神), “light’s kami,” in the second line and kagayaki (かがやき), “radiance,” in the fourth correspond as the agent of light and its activity. Between them stands the third line, oritachinu (降りたちぬ), “has descended and taken his stand,” so that all five lines form a mirror-like fold:
〈place—light—descent—light—place〉.
“Heaven” and “bottom” do not repeat the same thing. Rather, by setting the two poles of the cosmos against one another, each illuminates the other. The result is a method of contrast framed by correspondence between the opening and the close.
Moreover, when the poem’s thirty-one morae are counted, the sixteenth mora—the exact center of the poem—is the chi (ち) in oritachinu (降りたちぬ). The word tachi (立ち), “standing,” thus straddles the very center of the poetic form. There is no need to insist that this placement was consciously calculated, yet there is something especially beautiful in the fact that the word through which the kami descends and “stands” is itself standing at the poem’s waist. When the five lines are arranged one beneath another, the gaze itself descends from ama (天), “heaven,” at the top, through ori (降り), “descending,” in the middle, and down toward soko (底), “the bottom,” at the lowest point. The poem does not merely speak of a divine descent. The movement of reading the written words performs that descent as well, so that the poetic form itself becomes a kind of vertical mitate (見立て), a figurative construction through which one thing is seen as another.
The arrangement of the verbs likewise prevents the movement of light from coming to rest. Ama kakeri (天翔り), “coursing through heaven,” remains open in the continuative form and carries forward into the next line. It receives hikari no kami wa (光の神は), “as for the kami of light,” and proceeds to oritachinu (降り立ちぬ), “has descended and taken his stand.” Even within oritatsu (降り立つ), “to descend and stand,” two movements—ori (降り), “descending,” and tachi (立ち), “standing”—are folded into one. In the lower verse, wataru (渡る), “to cross, spread through, or pervade,” is then joined to kagayaki (輝き), “radiance.” The poem consequently unfolds through a sequence of verbal movements: traversing heaven, descending from above to below, standing at a particular point, and then spreading outward from that point through the whole domain. Ama kakeri (天翔り) crosses the sky, oritachinu (降り立ちぬ) establishes the vertical axis, and kagayaki wataru (かがやきわたる) extends the light across a plane and into depth. The resulting composition is therefore not merely an upward-and-downward motion but a three-dimensional filling of the whole of space.
The contrast between the perfective auxiliary nu (ぬ) in oritachinu (降り立ちぬ) and the wataru (わたる) of the fourth line is also important. Oritachinu closes a single decisive event by presenting it as already accomplished. Kagayaki wataru, by contrast, opens into the continuing condition of the light that has arisen from that event and is still spreading throughout the world. In the upper verse, the descent is completed; in the lower verse, its activity remains unfinished and continuous. The poem thus establishes a contrast between perfective aspect and durative, pervasive aspect. It is also worth noticing that all seven morae of the fourth line are occupied by the single compound expression kagayaki wataru (かがやきわたる). A word meaning “to spread throughout” literally spreads throughout the entire seven-mora line. Here again, content and form overlap.
Although every line settles properly into the classical pattern, the meaning and syntax do not stop at each line boundary. Ama kakeri (天かけり) does not complete a sentence by itself. The poem must pass through hikari no kami wa (光の神は) and continue to oritachinu (降りたちぬ) before the agent and destination of the motion become clear. In the same way, kagayaki wataru (かがやきわたる) reveals the full extent of its reach only when the fifth line, umi no soko ni mo (海の底にも), “even at the bottom of the sea,” is added. This is not ku-matagari (句跨り) in the narrow sense, in which a single word is divided across a five- or seven-mora boundary. It may nevertheless be understood as syntactic enjambment, for the sense of the sentence is handed across the boundaries between lines. Just as the light passes across the divisions between heaven, earth, and sea, the sentence itself flows across the boundaries of the five-seven-five-seven-seven form.
The fourth and fifth lines also employ inversion. In ordinary word order, the phrasing would be umi no soko ni mo, kagayaki wataru (海の底にも、かがやきわたる), “it shines throughout, even at the bottom of the sea.” Instead, the poem places the predicate first—kagayaki wataru / umi no soko ni mo (かがやきわたる／海の底にも)—and postpones the destination until the very end. The fourth line therefore first brings the expansion of the light itself into being. Only in the closing line does “the bottom of the sea” appear as the extreme point reached by that light. After being drawn along by the movement of the radiance, the reader’s gaze is plunged suddenly into the depths by the final seven morae.
Because the terminal and attributive forms of wataru (わたる) have the same sound and shape, the fourth line also produces a syntactic wavering. Heard as an independent predicate, it gives an inversion: “the light shines throughout—even at the bottom of the sea.” Heard as an attributive form, however, it momentarily raises the phrase kagayaki wataru umi (かがやきわたる海), a sea across which radiance spreads, bringing forward a vision in which the sea itself has become luminous. This is not a textbook kakekotoba (掛詞), a pivot word based upon distinct homophonous meanings, but it produces something close to a grammatical kake (掛け), in which the same sound-form carries both terminal and attributive functions. The reading in which light reaches the sea and the reading in which the sea itself is transformed into a field of light remain present without being completely separated from one another.
The closing phrase umi no soko ni mo (海の底にも) is not, strictly speaking, taigendome (体言止め), a noun-ending. The noun umi no soko (海の底), “the bottom of the sea,” is followed by the case particle ni (に) and the focus particle mo (も). It is more accurately described as joshi-dome (助詞止め), a particle-ending, or as an elliptical expression that prompts the mind to supply the predicate already placed before it. The mo (も) identifies an extreme point—“even at the bottom of the sea”—while at the same time enclosing within its implication the whole range that precedes that point: if the light reaches even there, it must also reach every place in between. The poem does not repeat that the light “has reached” or “has illuminated.” It simply stops at “even at the bottom of the sea.” Because of this, the radiance is not confined by the final line; it leaves an after-resonance in which it continues to spread beyond the poem itself.
The correspondence between the wa (は) at the end of the second line and the mo (も) at the end of the poem forms another quiet structural support. The wa in hikari no kami wa (光の神は) establishes kami as the topic of the poem. The mo in umi no soko ni mo (海の底にも) then extends the domain of that kami’s activity to include even the most remote region. Whereas wa singles out one agent, mo expands the range of that agent’s activity inclusively. The grammar of the poem thus moves from establishing kami to leaving nothing outside the light. This is not formal kakari-musubi (係り結び), however. Unlike zo, namu, ya, ka, and koso (ぞ・なむ・や・か・こそ), these particles do not alter the conjugated form of the ending. It is therefore better understood not as kakari-musubi but as a correspondence between two focus particles calling to one another from the poem’s first half and its close.
In sound, the syllable ri (り) recurs throughout the upper verse in kakeri (かけり), hikari (光), and ori (降り). The sound ka (か) also travels through kakeri (かけり), hikari (ひかり), kami (かみ), and kagayaki (かがやき). Thus, while light moves through the poem semantically, the sounds associated with that light are themselves handed from the first line into the fourth. Hikari (光), “light,” and kagayaki (かがやき), “radiance,” form a network of engo (縁語), associated words of brightness. Kakeri, ori, tachi, and wataru (翔り・降り・立ち・渡る) form a network of words of movement, while ama, umi, and soko (天・海・底) form a network of spatial terms. By placing different words one after another while never allowing the semantic field to break apart, these linked networks of engo support the sense that the entire poem flows in a single breath.
The word wataru (わたる) in particular retains not only the auxiliary-like sense of “extending throughout an entire domain,” but also its more concrete meaning of “crossing from this side to the other.” Because umi (海), “sea,” immediately follows it, a tangible image of light crossing the sea begins to move faintly behind the reading in which radiance simply extends everywhere. Once again, this cannot be called a strict kakekotoba, but it may be described as kakekotoba-like polysemy: adjacent words simultaneously activate more than one meaning within a single expression. Just as the sound ama (天), “heaven,” carries a distant echo of ama (海女), “woman diver,” the meanings of wataru are illuminated in return by the sea that follows it.
There is also a small modulation in the vowels. In kagayaki wataru (かがやきわたる), the open vowel a extends broadly, creating a bright resonance suggestive of light expanding outward. When the poem enters umi no soko ni mo (うみのそこにも), rounded and deeper u and o sounds become more prominent, and even the resonance of the voice seems to sink toward the seabed. The author’s intention cannot, of course, be determined from vowels alone. Yet the contrast between the expansive tone of the fourth line and the descending tone of the fifth becomes especially clear when the poem is spoken aloud. Not only the gaze but the resonance of the voice traces the movement from radiance into depth.
The expression hikari no kami (光の神), “kami of light,” also becomes more interesting when read not merely as personification but as a two-stage figuration. First, the abstract “light” is deified into a divine agent capable of coursing, descending, and standing. Once the poem enters the lower verse, however, the kami’s name is not repeated. The kami changes into the activity of kagayaki (かがやき), “radiance,” and dissolves into the world. The god is thus shown metonymically through an attribute that is also its activity. In the upper verse, light assumes a single form as a kami; in the lower verse, the kami loosens once again into light and spreads throughout all things. This movement—deification, descent, and metonymic diffusion—seems to open the field of vision from the amateru no ware (天照るの吾れ), “I, shining as heaven,” of Dōka 106 into the pervasively illuminated cosmos of Dōka 107.
This is therefore not a poem that foregrounds its technique through a fixed makurakotoba (枕詞), a particular utamakura (歌枕), honkadori (本歌取り), explicit kakari-musubi (係り結び), or taigendome (体言止め). Ama kakeri (天かけり) may be heard as a joshi-like (序詞的) or makurakotoba-like (枕詞的) opening. It is nevertheless more natural to understand it through the openness of its continuative form and the force of its mythic poetic diction than to classify it as a fixed classical pillow-word. The strength of this poem lies instead in the way its framing contrasts, the centrally placed tachi (立ち), its chain of verbs, its shift from completion into duration, its inversion and particle-ending, and its correspondences of sound and associated words all become one. Together they transform the thirty-one morae themselves into a path along which light travels from heaven to the bottom of the sea.
Grammatically, it is most precise to treat umi no soko ni mo (海の底にも) not as taigendome but as a particle-ending involving inversion and ellipsis, and to treat wa (は) and mo (も) not as formal kakari-musubi but as a correspondence between focus particles. The reading of waka through the combined analysis of sentence breaks, inversion, attributive suspension, and ellipsis constitutes a coherent analytical framework within Japanese linguistics. Inversion in waka also has the effect of strongly impressing upon the listener the phrase delayed until the end. Although wa and mo are classified as kakari-joshi (係助詞), focus particles, they do not produce the change in the final conjugated form found in kakari-musubi governed by zo, namu, ya, ka, or koso (ぞ・なむ・や・か・こそ).
A one-sentence colloquial summary
“The kami of light who courses through heaven has descended to earth, and that radiance reaches all the way to the deepest bottom of the sea.”
Speech Act Theory
Viewed through Austin’s (1962) theory of speech acts, the locutionary act of this poem is first of all the statement of a cosmic event: the hikari no kami (光の神), “kami of light,” who courses through heaven has already oritachi (降り立ち), “descended and taken their stand,” and that radiance extends even to umi no soko ni mo (海の底にも), “the bottom of the sea.” What matters, however, is that meaning is carried not only by the semantic content but also by the way the utterance is constructed. At the fold between the kami-no-ku (上の句), the upper verse, and the shimo-no-ku (下の句), the first and second lines, ama kakeri / hikari no kami wa (天かけり／光の神は), fold back into the fourth, kagayaki wataru (かがやきわたる). The kami first placed before the listener as a name opens into light as activity. At the same time, the third line, oritachinu (降りたちぬ), is given its point of arrival by the fifth, umi no soko ni mo (海の底にも). The motion in the heavens and the arrival at the seabed are thus folded neatly into a single field of meaning.
Read as an illocutionary act, the poem is doing more than describing an event. It is proclaiming the descent and declaring a vision of the world in which light reaches throughout the entire domain. The third line, oritachinu (降りたちぬ), is especially important as the pivot that produces a strong cut. The descent is stated there as something already completed, after which the fourth and fifth lines open the range of its effects. Moreover, the sound ama (あま) carries both the resonance of heaven and a faint movement toward the sea. Even if this cannot be called a strict textbook kakekotoba, it creates an acoustic bridge that joins the upper and lower worlds in advance.
Finally, as a perlocutionary act, the poem produces within the scene of reading not merely awe or consolation but a change in one’s sense of what can be illuminated. The soko (底), “bottom,” of the sea begins to resonate as more than a metaphor for a distant place. It comes to include those strata of training to which light has not yet reached: layers of pain and turbidity that have not yet become words. Received in this way, the poem’s activity does not end as an explanation of cosmology. It rises instead as a quiet orientation—a direction toward carrying the light of aiki (合気) into even the most difficult-to-see depths.
Coda
What remains at the close of this poem may be less the splendor of light than the question, “Where does it take its stand?” The kami that courses through heaven in ama kakeri (天かけり) does not merely descend. It also tachi (立ち), “stands.” Moreover, the word tachi straddles the exact center of the poem’s thirty-one morae. Light ceases to be only a distant heavenly principle when it gains a standing-place within the body and the world; only then does it become the activity of kagayaki wataru (かがやきわたる), radiance spreading throughout. Aiki as Cosmic Principle has not yet descended into training merely because it has been explained or intellectually understood. It becomes an actual working presence when it takes its stand within breath, posture, maai, touch, and one’s response to another person.
The mo (も) in umi no soko ni mo (海の底にも), “even at the bottom of the sea,” is therefore not simply cosmic hyperbole. It is a quiet test of whether one is content to illuminate only what is visible, orderly, and easily explained. One’s pain, anger, shame, fear, and the resentment or misunderstanding that has sunk to the bottom of a relationship are not necessarily erased by the light. Rather, they are no longer abandoned outside it. Pervasive illumination does not mean denying darkness. It means restoring even darkness to relation and receiving it anew as a place to which Wagō Bika (和合美化), “Harmonization and Beautification,” may extend.
In this sense, the Six Primers appear to be condensed into the verb “to descend and stand” and the particle “even.” Cosmic Principle and the source of Supreme Love do not remain in heaven; they descend into the body as Dōjō. Their light passes into the inward depths as Shinkon Ichinyo (心魂一如), “Heart-mind and Spirit, Inseparable”; it extends between people as Kami ya Hito to no Aiki (神や人との合気), “Aiki with Kami / Another / Others”; and through Harmonization and Beautification, it gathers even what had previously been cut away back into a single world. “Standing” is the moment at which principle acquires a body. “Even” is the widening through which nothing is left outside its activity.
The completed action of oritachinu (降り立ちぬ), “has descended and taken its stand,” and the continuing activity of kagayaki wataru (かがやきわたる), “radiance spreads throughout,” also reveal two different times of practice. From the side of the source, the light has already descended. From the side of the practitioner, however, the work of allowing that light to pass through every part of the body, the depths of heart-mind and spirit, and the space between oneself and others is not yet finished. We do not possess the light; we become its passage. To polish the body as dōjō is perhaps to continue standing between this “already” and this “still.”
The closing ni mo (にも) is therefore less a conclusion than an opening. If the radiance reaches even the bottom of the sea, then nothing lying between heaven and that depth remains outside the light. Heaven, earth, body, heart-mind, other people, and those depths that have not yet become words are joined along a single vertical axis. Dōka 107 does not present a figure merely looking upward and awaiting the arrival of light. It presents a person being asked how far the light that has already descended can travel through them. Aiki may be the continuing act of answering that question not through technique alone, but through the whole of one’s way of living.
