解説
第136首「すさの男の／玉の剣は／世にいでて／東の空に／光り放てり」は、“玉（たま）”＝宝玉／みたま（霊）の掛けを帯びた玉の剣が「世に出でて」（潜勢から顕現へ）東天へ向けて「光り放てり」（…て＋あり＞…てり：結果‐存続）と輝度を保つ姿を描きます。東の空は古典的に暁・更新のトポスで、ときにあづまの読みを許すゆえ辺境／前線の含意も差しこまれる、とページ注は押さえています。背後の神話は、須佐之男命が八岐大蛇の尾から得た天叢雲剣（後の草薙剣）であり、ゆえに玉の剣は宝玉の光沢＋霊威を帯びた御剣として機能する——短い五句に顕現→志向→照射の弧を畳みこむ構図です。
植芝盛平の六つのプライマーに糸を通すと、ここでの御剣は稽古の運転図になります。プライマーの第一原理〈武＝宇宙原理〉：“神ながら”の秩序に合う剣＝光を放つ原理としての武。プライマーの第二原理〈神や人との合気〉：東（暁）へ向ける志向は、神や対人の場を更新へ導く照明として働く。プライマーの第三原理〈心魂一如〉：声・息・身が一拍に揃ってこそ光が“放たれ”続ける（…てりの持続相）。プライマーの第四原理〈和合美化〉：剣は斬滅でなく和と美へ照らす道具。プライマーの第五原理〈体＝道場、心＝修業者／修行者／学び手〉：“世に出でて”を毎稽古の“ここで出す”へ落とし、基本型で放つ角度／間／拍を磨く。プライマーの第六原理〈「至愛」の源に順う〉：顕現した光（技）を誰を生かすために放つのかを定める北極星。ページは玉＝jewel／tama（みたま）の二重焦点、放てりの古典形、東の読み分けまで示し、御剣＝光の倫理へ導いています。
直前の三首との連関も鮮明です。第133首が「御親の仕組は成り終えぬ……吾はしとめん」と完成の封を誓い、第134首が「松竹梅—錬り清め……身変るの水火」で鍛錬×禊による変容を説き、第135首が「真空と空のむすび」を知の土台と定めた流れの上で、第136首は「世にいでて」と剣＝光を実地へ顕現させ、「東の空」へ再生の方向を明指します。須佐之男の御剣がアマテラスの光（東天の暁）と呼応する読みは、レガリア（草薙）と日の出の象徴連関としてページ注が補強——斬るためではなく、照らすために出る御剣が合気の実践倫理だ、と集約できます。
口語要約のひとこと
「スサノオの玉の剣は、世に出て——東の空に、光を放っている。」
修辞補説――句跨り・本説取り・異訓の放光
第136首でさらに押さえるべき第一の仕掛けは、五・七・五・七・七に一音の過不足もない定型を、結句まで一つの文が貫く「一首一文」の構えです。各句末は「の／は／て／に／り」と進み、初句の「の」は次句の体言を、第二句の「は」は後続する述語を、第三句の「て」は次の動作・状態を、第四句の「に」は結句の述語を待つ。主述の完結は「光り放てり」まで鞘に納められ、結句に至って初めて抜き放たれます。したがって「世にいでて」は意味上・朗誦上の折り目としては強く働くものの、接続助詞「て」が文を先へ渡すため、厳密な句切れ分類では「三句切れ」ではなく「句切れなし」と見るのが堅いところです。ただし第三句は短歌の「腰句」に当たり、ここで上句の御剣が下句の東天へ向きを変えるため、文法的には切れず、意味としては折れるという二重の腰が生まれています。
この一首一文を支えるのが、対称的な句跨りです。「すさの男の｜玉の剣は」は、初句末の「の」が第二句へ意味を越境させ、「東の空に｜光り放てり」は、第四句末の「に」が結句の述語を呼びこみます。第一・二句と第四・五句が同じように句境をまたぐため、第三句「世にいでて」が両者を折り合わせる蝶番となります。七音句の内部にも、「玉の｜剣は」が三・四、「東の｜空に」が四・三、「光り｜放てり」が三・四という微細な反転があり、凝縮した御剣がいったん反転して東天へ開き、再び三・四の律で放光へ収まる。上句—下句の「折り」は意味の対応だけでなく、句内拍の反転としても組まれています。
助詞の反復も、単なる文法材料ではなく修辞的な変奏です。「の」は三度現れますが、「すさの男の」では所有・由来・神格との所属を、「玉の」では性質・美称・霊威を、「東の」では方位による空の限定を担います。同じ「の」が、神名→霊的性質→宇宙的方位へと機能を移してゆく。一方、「世に」の「に」は顕現の到達点、「空に」の「に」は放光が成立する場所を示し、同じ格助詞が〈運動の行先〉から〈光の所在〉へ転じます。上句の「の」が御剣へ力を内向きに凝集し、第三・四句の「に」がその力を世界と空へ外向きに展開する——「は」が御剣を取り立て、「て」が運動を継ぎ、「り」が光を定着させる、助詞そのものによる顕現→定位→存続の配線です。
既出の玉／魂（たま）に加えて、最も有力な追加の掛詞は「世（よ）／夜（よ）」です。表記された第一義はもちろん「世に出づ」＝世界へ顕現することですが、「夜に出でて／東の空に／光り放てり」と耳で重ねれば、夜のただ中から東天の暁光が現れる第二の景が成立します。「よ」は世・夜・代・節などを掛け得る古典和歌の代表的な同音語群であり、この歌では後続する「東」「空」「光」が夜の読みを孤立させず、夜→暁という時間軸として支えます。したがって第三句は、神剣が人界へ出現する宇宙論的な「世」と、暗がりから光が生まれる時間的な「夜」を一音に畳みこむ腰句となります。
縁語も一系列ではなく、二つの語群が交差しています。ひとつは「すさの男—玉—剣—放つ」という神剣・武威の系列、もうひとつは「出づ—東—空—光」という日の出・照明の系列です。「玉」と「光」は宝玉の輝きで結ばれ、「剣」と「放つ」は武器や力を外へ解き放つ運動で結ばれます。その二系列の結節点が「放つ」です。「放つ」は光を発する語であると同時に、矢・声・力などを身から離して外へ送り出す語でもあるため、御剣の武的運動を斬撃ではなく放光へ転義させます。また「出でて」と「放てり」は、ともに内から外へ向かう動詞として照応し、第三句で姿を現したものが、結句で作用そのものを外へ送り出す二段の顕現をつくります。
「光り」の品詞境界にも小さな両義性があります。名詞「光」の後の目的格「を」を韻律上省いた「光（を）放てり」と取れば、御剣が光を放出する構文となります。他方、動詞「光る」の連用形を複合動詞の前項とする「光り放つ」と取れば、光ることと放つことが一動作へ融合します。前者では〈御剣→光〉という対象の移送が立ち、後者では御剣そのものが放光運動になります。名詞か動詞かを完全に固定しない表記が、光を「放たれるもの」と「放つ働き」の両方に置いています。
音韻面では、「東」を「ひがし」と読むと「ひがし／ひかり」が鮮明な頭韻をつくります。両語はいずれも三拍で、「ひ—が—し／ひ—か—り」と初拍の「ひ」を共有し、母音列もおおむねイ―ア―イと響き合うため、東という方位が発音された時点で、次句の光がすでに音として立ち上がります。これに対し「あづま」と読めば、この頭韻は退きますが、東国・東歌・辺境という歴史地理的な地平が前へ出る。「ひがし」も「あづま」も三拍なので、「東の空に」はどちらでも七音を保ちます。つまり異訓は韻律を壊さず、〈ひがし＝光との音韻照応〉と〈あづま＝東国との文化的照応〉を選び分けます。これは同音異義を重ねる狭義の掛詞ではなく、一字に二つの訓を宿す「異訓による二重構え」です。
神話的典拠の扱いは、本歌取りよりも「本説を取る」方法に近いものです。特定の先行和歌の語句を取りこむ本歌取りとは異なり、この首は八岐大蛇、切断された尾、十拳剣、天叢雲剣・草薙剣という物語の筋を一語も説明せず、「すさの男の／玉の剣」の二句だけで背後に立ち上げます。物語や説話の場面を和歌へ取りこむ方法は「本説を取る」と整理されるため、ここでは「神話的本説取り」あるいは「本説取りに近い引喩」と呼ぶのが適切です。 剣の固有名をあえて置かない省略法によって、それは大蛇の尾から現れた剣であると同時に、須佐之男の霊威そのもの、三種の神器、さらに稽古に顕現する合気の御剣までを重ね得る代称となっています。
見立ての層では、御剣が暁光に見立てられるだけでなく、暁そのものも抜き放たれた剣に見立て返されます。「東の空」は単なる背景ではなく、御剣の光が現象となる巨大な鞘口です。第三句で世／夜へ出た剣が、第四句で東天へ据えられ、第五句で光を抜き放つため、日の出は宇宙規模の抜剣となり、抜剣は破壊ではなく夜を明けへ変える照明となります。さらに「玉—剣—光」という配列は、確定的な列挙ではないものの、玉・剣・鏡という三種の神器の連想圏を開きます。「玉」と「剣」は語面に現れ、「鏡」は東天の光を受け、返し、遍く照らす不在の第三項として暗示される——明示されないものまで光によって呼び出す、省筆の余情です。
用語上の境界も明確にしておく必要があります。「玉の」はここでは貴重・美麗・高貴を示す美称的な修飾としては強く働きますが、「あしひきの―山」「ひさかたの―天」のように特定の被修飾語へ慣用的に掛かる、厳密な枕詞と断定する根拠は乏しいところです。「玉」には美麗・貴重・高貴を示す接頭語的用法があるため、「枕詞」より「美称」または「枕詞的修飾」とする方が安全です。 同様に「東の空」は、暁・更新・東国の記憶を帯びた方位的トポスではあっても、具体的な名所を指す歌枕ではありません。第一・二句は御剣を直接限定するため序詞ではなく、係助詞による結びもなく、結句は名詞ではないため体言止めでもありません。「東」のひがし／あづま、「空」のそら／くうを往還する読みも、同じ音に二義を重ねる掛詞ではなく、それぞれ異訓と表記一字の意味重層として区別されます。
なお結句の形態は、「放てり」＝四段活用動詞「放つ」の已然形「放て」＋完了・存続の助動詞「り」と解析します。「て＋あり」が縮約した形とするのは「たり」の説明と混線するため、既存注の「…て＋あり＞…てり」は改めた方が明確です。完了・存続の「り」は四段動詞の已然形に接続し、「放つ」の已然形も「放て」となります。 したがって結句は体言止めではなく、終止形「り」による助動詞終止です。文法としてはここで一首を閉じながら、存続相としては光を閉じず、「すでに放たれ、いまなお放たれている」という状態を歌外へ残します。
以上を重ねると、第136首の修辞は、御剣について説明するだけでなく、統辞そのものを御剣の運動にします。初句から第四句まで主述を延ばして霊威を鞘内に集め、腰句で世／夜へ顕し、異訓と頭韻によって東と光を結び、結句で述語を抜き放つ。上句は神名から御剣へ凝縮し、下句は御剣から東天へ拡張する——その折りのただ中で、「斬る剣」が「照らす剣」へ変わる瞬間そのものが、一首の文法として光り放たれています。
発話行為理論
オースティン（Austin, 1962）の三分法で読むと、第136首の発話行為（locutionary）は、五七五七七の声として「すさの男の／玉の剣は」を上句の御剣、「東の空に」を下句の天域へ折り返し、第三句「世にいでて」を折り目として据えるところにあります。第一・二句の「の／は」は神名から御剣へ霊威を集め、第四句の「の／に」は東天という暁の場へ霊威を受け渡す。第三句の「出でて」と第五句の「放てり」は、顕現と照射を響き合わせる動詞の対であり、明示の切れ字は立たないものの、第三句の連用接続が切れとして働き、上句の潜勢を下句の結果存続へ渡します。玉は宝玉／みたま、空は天穹／空性、東はひがし／あづまの二重焦点を帯び、掛詞的な厚みとして御剣の声を重ねます。
発話内行為（illocutionary）の層では、第136首は単なる叙述ではなく、顕現の宣言です。須佐之男の荒ぶる霊威が玉の剣として世に出る、という神話的命題は、合気の剣を斬滅の道具から、東天を照らす原理へ転じさせる発話内の力をもちます。上句—下句の折りは、その力の配線図となる。第一・二句の御剣は第四句の東天へ折り返され、第三句の「世にいでて」は第五句の「光り放てり」へ折り返される。ゆえに御剣は、ただ出現したのではなく、すでに放光の働きとして成っている。Austin のいう force は、まさにこの「言われた内容」を「何として受け取るべきか」へ変える圧として現れます。
発話媒介行為（perlocutionary）の層では、当該宣言が畏敬、姿勢の転換、稽古の照明を生みます。第三句の切れによる一拍の留保は、御剣の出現を息の間に置き、第五句の「光り放てり」で結果存続の明るさへ解き放つ。玉／みたまの掛けは、物質の剣を霊威の剣へ、東の空は、戦いの地平を暁の更新へ変える。ここにおける発話媒介行為は、聞く身に「剣とは斬るためのもの」という反応をほどき、「剣とは照らすために出るもの」という合気の倫理を生じさせる働きです。斬滅ではなく和合美化へ、攻撃ではなく照明へ——第136首の御剣は、世に出でてなお、東天に光り放ち続けます。
コーダ
第136首の御剣は、過ぎ去った神話の遺物として鞘に納められているのではない。「すさの男の／玉の剣は」と神名から霊威を凝集し、「世にいでて」で世／夜の境へ顕れ、「東の空に／光り放てり」で暁の働きとして定着する。文法上、一首は結句の助動詞「り」によって閉じられる。しかし、その完了・存続の相は光を閉じない。歌は読み終えられても、すでに放たれた御剣の光は、なお東天に放たれ続けています。
ここで起こる転義は、剣の力を捨てることではありません。須佐之男の荒ぶる霊威は消去されず、誰かを断つための力から、夜を明けへ開く力へと結び直されます。「放つ」は斬撃の語域を越え、光、声、息、気を身体から世界へ送り出す動詞となる。したがって玉の剣は、武器でありながら武器性を越え、相手を暗闇として排除するのではなく、自他の立つ場そのものを見えるものへ変える御剣となります。荒ぶる力は鎮められて無くなるのではなく、照明の働きとして正しく現れ直すのです。
第133首の完成、第134首の錬り清めと身変り、第135首の真空と空のむすびを受け、第136首は、それらを潜勢のままに残さず「世に出す」段階へ進みます。体という道場において鍛えられ、心という学び手によって受け取られ、声・息・身の一拍に結ばれたものだけが、技として東天へ放たれる。ここで「東」は単なる方角ではなく、稽古がつねにもう一度始まり得る方位です。そして「至愛」は、その光を誰のために、何を生かすために放つのかを定める北極星となります。
ゆえに、この道歌が求める抜剣は、敵を切り分ける決断ではなく、世界を夜から朝へ折り返す決断です。御剣を世に出すとは、勝利の証を掲げることではない。自らの一挙一動を、自分と他者の双方を生かすに足る明るさへ変えることです。須佐之男の玉の剣は、遠い神代に一度だけ東の空を照らしたのではありません。正しく稽古されるたび、いまここに再び抜き放たれ、斬らずして道を明らかにする——その不断の放光こそが、「光り放てり」の歌外へ続く余韻なのです。
English Translation
Commentary
Dōka 136, Susanoo no / tama no tsurugi wa / yo ni idete / higashi no sora ni / hikari hanateri (すさの男の／玉の剣は／世にいでて／東の空に／光り放てり), depicts the jewel-sword—charged with the pivot of tama as both jewel and mitama (spirit)—coming “forth into the world,” yo ni idete (「世に出でて」), from latency into manifestation, and sustaining its radiance toward the eastern heavens through hikari hanateri (光り放てり), which the existing note reads as …te + ari > …teri (…て＋あり＞…てり), marking a resulting state that endures. The eastern sky is classically a topos of dawn and renewal; because higashi (東) may at times admit the reading azuma (あづま), the page note observes that undertones of the eastern provinces, the frontier, or the forward line may also enter the poem. Behind it stands the myth of Susanoo no Mikoto (須佐之男命), who found Ame no Murakumo no Tsurugi (天叢雲剣)—later Kusanagi no Tsurugi (草薙剣)—within the tail of Yamata no Orochi (八岐大蛇). The “jewel-sword” therefore functions as a sacred sword bearing both the sheen of a jewel and the authority of spirit: a composition that folds the arc of manifestation → orientation → illumination into five compact lines.
Threaded through Morihei Ueshiba’s Six Primers, this sacred sword becomes an operating diagram for practice. The First Primer, “Bu = Cosmic Principle”: a sword aligned with the order of kannagara (神ながら), and thus bu as a principle that casts light. The Second Primer, “Aiki with Kami / Another / Others”: its orientation toward the east—toward dawn—works as an illumination that guides the inter-kami and interpersonal fields toward renewal. The Third Primer, “Heart-mind and Spirit, Inseparable”: only when voice, breath, and body are brought into a single beat can the light continue to be “cast forth,” as expressed by the enduring aspect of …teri (…てり). The Fourth Primer, “Harmonization and Beautification”: the sword is not an instrument of annihilation, but one that illuminates the way toward harmony and beauty. The Fifth Primer, “Body = Dōjō; Heart-mind = Practitioner / Ascetic / Learner”: yo ni idete (「世に出でて」), “coming forth into the world,” is brought down into the act of koko de dasu (ここで出す), “bringing it forth here,” in every practice, refining through the basic forms the angle, interval, and beat through which it is released. The Sixth Primer, “Follow the Source of Supreme Love”: the North Star that determines for whose life the manifested light—the technique—is to be cast forth. By presenting the double focus of tama as jewel and mitama, the classical form of hanateri (放てり), and the alternative readings of “east,” the page leads toward an ethic of the sacred sword as light.
Its relation to the immediately preceding three poems is equally clear. Dōka 133 vows to affix the final seal of completion with mi-oya no shikumi wa nari oenu……ware wa shitomen (御親の仕組は成り終えぬ……吾はしとめん), “the Divine Parent’s design has reached completion … I shall consummate it.” Dōka 134 teaches transformation through tempering joined to misogi in matsu-take-ume—neri kiyome……mi kawaru no suika (「松竹梅—錬り清め……身変るの水火」), “pine, bamboo, and plum—temper and purify … the water and fire through which the body changes.” Dōka 135 establishes shinkū to kū no musubi (「真空と空のむすび」), “the joining of true vacuum and emptiness,” as the ground of knowing. Upon that sequence, Dōka 136 brings the sword as light into practical manifestation through yo ni idete (「世にいでて」), and explicitly indicates the direction of regeneration through higashi no sora (「東の空」), “the eastern sky.” The reading in which Susanoo’s sacred sword answers the light of Amaterasu—the dawn of the eastern heavens—is reinforced by the page note as a symbolic relation between the regalia, Kusanagi, and sunrise. The practical ethic of aiki can therefore be gathered into a single proposition: the sacred sword comes forth not to cut, but to illuminate.
A colloquial summary in one line
“Susanoo’s jewel-sword has come forth into the world—and there, in the eastern sky, it is shining forth.”
Rhetorical supplement: Enjambment, source-narrative allusion, and the light of variant readings
The first further device to be noted in Dōka 136 is its “one-poem, one-sentence” construction, isshu ichibun (一首一文): a single sentence passes through the entire faultless 5–7–5–7–7 form without a mora in excess or deficit, reaching completion only in the concluding line. The line endings proceed as no / wa / te / ni / ri (の／は／て／に／り). The no (の) at the end of the first line awaits the noun of the second; the wa (は) of the second awaits the predicate that follows; the te (て) of the third carries the sentence onward into the next action or state; and the ni (に) of the fourth waits for the predicate of the concluding line. The subject–predicate relation remains enclosed within its scabbard until hikari hanateri (光り放てり), and only upon reaching that final line is it drawn fully forth. Consequently, yo ni idete (世にいでて) functions strongly as a fold in meaning and recitation, yet because the conjunctive particle te hands the sentence onward, strict classification by kugire (句切れ) favors kugire nashi (句切れなし), “no formal cut,” rather than sanku-gire (三句切れ), a “third-line cut.” The third line is nevertheless the poem’s koshi-ku (腰句), its “waist line”: here the sacred sword of the upper verse turns toward the eastern heavens of the lower verse. A double waist is thus formed—grammatically unbroken, semantically folded.
This single-sentence construction is supported by symmetrical enjambment, or ku-matagari (句跨り). In Susanoo no | tama no tsurugi wa (すさの男の｜玉の剣は), the no at the end of the first line crosses the boundary into the second; in higashi no sora ni | hikari hanateri (東の空に｜光り放てり), the ni at the end of the fourth summons the predicate of the fifth. Because the first and second lines cross their boundary in the same manner as the fourth and fifth, the third line, yo ni idete (世にいでて), becomes the hinge that folds the two structures together. Within the seven-mora lines there are further minute reversals: tama no | tsurugi wa (玉の｜剣は) divides 3–4; higashi no | sora ni (東の｜空に) divides 4–3; and hikari | hanateri (光り｜放てり) returns to 3–4. The sacred sword, first compressed into a 3–4 measure, reverses into 4–3 as it opens toward the eastern heavens, then settles once more into 3–4 as radiance is cast forth. The fold between the upper and lower verses—kami-no-ku (上句) and shimo-no-ku (下句)—is therefore organized not only through semantic correspondence, but through the reversal of the pulse within the lines themselves.
The repetition of particles is likewise not mere grammatical material, but rhetorical variation. No (の) appears three times. In Susanoo no (すさの男の), it marks possession, origin, and affiliation with the deity; in tama no (玉の), it conveys quality, laudation, and numinous authority; in higashi no (「東の」), it delimits the sky by cosmic direction. The same no shifts its function from divine name → spiritual quality → cosmic orientation. The ni (に) of yo ni (世に) indicates the destination at which manifestation arrives, whereas the ni of sora ni (空に) indicates the place in which illumination takes form. The same case particle turns from the destination of motion to the locus of light. The no of the upper verse gathers power inward into the sacred sword, while the ni of the third and fourth lines unfolds that power outward into the world and sky. Wa (は) sets the sword apart as the poem’s theme; te (て) carries its motion onward; and ri (り) establishes the light as an enduring state. The particles themselves wire the sequence manifestation → emplacement → continuance.
In addition to the already noted pivot of jewel and spirit in tama (玉／魂), the strongest additional kakekotoba (掛詞) is yo as “world” and “night,” yo / yo (世／夜). The primary written meaning is, of course, yo ni izu (世に出づ), to manifest within the world. Heard, however, as yo ni idete / higashi no sora ni / hikari hanateri (夜に出でて／東の空に／光り放てり)—“coming forth into the night, casting light into the eastern sky”—a second scene comes into being. Yo is one of the representative homophonic clusters of classical waka, capable of bearing “world,” “night,” “age,” “generation,” or “juncture.” Here the succeeding words “east,” “sky,” and “light” prevent the nocturnal reading from standing in isolation; together they sustain the temporal axis night → dawn. The third line therefore becomes a waist line that folds into a single sound both the cosmological “world” into which the divine sword manifests and the temporal “night” from whose darkness light is born.
The poem’s engo (縁語), or associated diction, likewise does not form a single series. Two lexical constellations intersect. One is the sequence Susanoo—jewel—sword—release, Susanoo—tama—tsurugi—hanatsu (すさの男—玉—剣—放つ), belonging to the sacred sword and martial authority. The other is emerge—east—sky—light, izu—higashi—sora—hikari (出づ—東—空—光), belonging to sunrise and illumination. “Jewel” and “light” are joined through the gleam of a precious stone; “sword” and “release” are joined through the outward movement of a weapon or force. The point at which these two series meet is hanatsu (放つ), “to release” or “to send forth.” The verb signifies the emission of light, but also the sending forth of an arrow, a voice, or a force away from the body. It therefore redirects the martial movement of the sacred sword away from the semantic field of the strike and into that of radiance. Idete (出でて) and hanateri (放てり) also correspond as verbs that move from within to without. What appears in the third line sends not only its form but its operation itself outward in the fifth, producing a two-stage manifestation.
There is a further small ambiguity at the boundary of grammatical category in hikari (光り). If the phrase is understood as the noun “light,” with the accusative particle o (を) omitted for metrical reasons—hikari o hanateri (「光を放てり」)—the construction states that the sacred sword emits light. If, however, hikari is taken as the continuative form of the verb hikaru (光る), serving as the first element of the compound verb hikari-hanatsu (「光り放つ」), shining and releasing are fused into a single action. In the former reading, the relation sacred sword → light stands forth as the transmission of an object; in the latter, the sacred sword itself becomes the motion of illumination. By not fixing the word-class boundary completely, the orthography places light both as “that which is emitted” and as “the act of emitting.”
On the phonological level, reading “east” as higashi (ひがし) produces clear alliteration with hikari (ひかり), “light.” Both words contain three morae and share the initial hi (ひ); their vowel sequences likewise broadly echo one another as i–a–i. The moment the direction “east” is pronounced, the light of the following line has already begun to rise as sound. If the character is instead read azuma (あづま), this alliteration recedes, but the historical and geographical horizon of the eastern provinces, the Azuma-uta (東歌), and the frontier comes forward. Because both higashi and azuma contain three morae, higashi no sora ni (東の空に) retains its seven-mora form under either reading. The variant reading therefore leaves the meter intact while allowing a choice between higashi, with its phonological correspondence to light, and azuma, with its cultural correspondence to the eastern provinces. This is not a kakekotoba in the narrow sense of layering different meanings upon the same sound, but a “double construction through variant readings,” ikun ni yoru nijū-gamae (「異訓による二重構え」).
The treatment of the mythic source is closer to “taking a source narrative,” honzetsu o toru (本説を取る), than to honkadori (本歌取り). Unlike honkadori, which incorporates words or phrases from a specific earlier waka, this poem spends no words explaining the narrative of Yamata no Orochi (八岐大蛇), the severed tail, Totsuka no Tsurugi (十拳剣), or Ame no Murakumo no Tsurugi and Kusanagi no Tsurugi (天叢雲剣・草薙剣). The two lines Susanoo no / tama no tsurugi wa (すさの男の／玉の剣は) are sufficient to raise the entire story behind the poem. Because the incorporation of a scene from a tale or narrative into waka is classified as honzetsu o toru, it is appropriate here to speak of “mythic honzetsu-dori” or an allusion approaching honzetsu-dori. The deliberate omission of the sword’s proper name allows “the jewel-sword” to function as a periphrastic designation capable of superimposing several identities: the sword revealed within the serpent’s tail, Susanoo’s numinous authority itself, one of the Three Sacred Treasures, and the sacred sword of aiki manifested within practice.
At the level of mitate (見立て), the sacred sword is not only figured as the light of dawn; dawn itself is figured back as a sword drawn from its sheath. The “eastern sky” is not merely a background, but the immense mouth of the scabbard through which the light of the sacred sword becomes phenomenon. In the third line, the sword emerges into the world—or night. In the fourth, it is set within the eastern heavens. In the fifth, it draws and releases light. Sunrise thereby becomes a drawing of the sword on a cosmic scale, while the drawing of the sword becomes not destruction, but an illumination that changes night into dawn. The sequence jewel—sword—light, tama—tsurugi—hikari (玉—剣—光), also opens the associative field of the Three Sacred Treasures—jewel, sword, and mirror—although it is not a definitive enumeration. The jewel and sword appear explicitly. The mirror remains an absent third term, suggested by the light of the eastern heavens that it receives, returns, and spreads without limit. Even that which is not stated is summoned through light: the suggestive aftertone created through elliptical restraint.
The boundaries of the technical terminology should also be kept clear. Tama no (玉の) strongly functions here as a laudatory modifier expressing preciousness, beauty, and nobility. There is, however, insufficient basis for declaring it a strict makurakotoba (枕詞) of the conventional kind that attaches habitually to a fixed headword, as in ashihiki no—yama (あしひきの―山), “foot-dragging—mountain,” or hisakata no—ama (ひさかたの―天), “far-distant—heaven.” Because tama has prefix-like uses expressing beauty, value, and nobility, it is safer to call it a laudatory epithet or a makurakotoba-like modifier. Likewise, “the eastern sky” bears the memories of dawn, renewal, and the eastern provinces as a directional topos, but it is not an utamakura (歌枕) designating a specific celebrated place. The first and second lines directly delimit the sacred sword and therefore do not constitute a joshi (序詞), or prefatory phrase. There is no kakarimusubi (係結び), no binding relation governed by an emphatic particle, and because the concluding line does not end in a noun, it is not taigendome (体言止め). The movement between higashi and azuma for “east,” and between sora and kū for “sky” or “emptiness,” should likewise be distinguished from a kakekotoba: these are variant readings and layers of meaning carried by a single written graph, not two meanings superimposed upon an identical sound.
The morphology of the concluding line must also be clarified. Hanateri (放てり) is analyzed as the realis form hanate (放て) of the quadrigrade, or yodan, verb hanatsu (放つ), followed by the auxiliary ri (り), expressing completion and continuance. Explaining the form as te + ari > teri (て＋あり＞てり) confuses its derivation with that of tari (たり), and the existing annotation would be clearer if revised accordingly. The auxiliary ri attaches to the realis form of a quadrigrade verb, and the realis form of hanatsu is indeed hanate. The concluding line is therefore not taigendome, but a finite auxiliary conclusion in the terminal form ri. Grammatically, the poem closes there; aspectually, however, it does not close the light. It leaves beyond the bounds of the poem the state “already cast forth, yet still being cast forth now”—sude ni hanatare, ima nao hanatarete iru (「すでに放たれ、いまなお放たれている」).
Taken together, these devices show that the rhetoric of Dōka 136 does not merely explain the sacred sword: its syntax itself performs the sword’s motion. From the opening line through the fourth, the completion of the subject and predicate is delayed, gathering numinous authority within the scabbard. At the waist line, that authority manifests within the world and the night. Variant readings and alliteration bind east to light. In the concluding line, the predicate is drawn and released. The upper verse condenses divine name into sacred sword; the lower verse expands sacred sword into the eastern heavens. At the center of that fold, the very moment in which the “sword that cuts,” kiru tsurugi (斬る剣), becomes the “sword that illuminates,” terasu tsurugi (照らす剣), is itself cast forth as the grammar of the poem.
Speec Act Theory
Read through Austin’s (1962) tripartite account, the locutionary act of Dōka 136 lies in the way its 5–7–5–7–7 utterance folds Susanoo no / tama no tsurugi wa (すさの男の／玉の剣は), the sacred sword of the upper verse, back toward higashi no sora ni (東の空に), the celestial domain of the lower verse, while establishing the third line, yo ni idete (世にいでて), as their fold. The no / wa (の／は) of the first and second lines gather numinous authority from the divine name into the sacred sword; the no / ni (の／に) of the fourth line deliver that authority into the eastern heavens as the field of dawn. Idete (出でて) in the third line and hanateri (放てり) in the fifth form a pair of verbs that answer one another as manifestation and illumination. Although no explicit kireji (切れ字) stands in the poem, the connective continuation of the third line performs a cutting function, transferring the latency of the upper verse into the resulting continuance of the lower. Tama bears the double focus jewel / mitama; sora and kū bear sky / emptiness; higashi and azuma bear two orientations of “east.” These layers give the utterance a kakekotoba-like density through which the voice of the sacred sword is superimposed upon itself.
At the level of the illocutionary act, Dōka 136 is not merely a description, but a declaration of manifestation. The mythic proposition that Susanoo’s fierce numinous authority comes forth into the world as the jewel-sword gives the utterance the force to transform the sword of aiki from an instrument of annihilation into a principle that illuminates the eastern heavens. The fold from upper to lower verse becomes the wiring diagram of that force. The sacred sword of the first and second lines is folded toward the eastern heavens of the fourth; yo ni idete (世にいでて) in the third is folded toward hikari hanateri (光り放てり) in the fifth. The sacred sword has therefore not merely appeared: it has already become the operation of illumination. What Austin calls “force” appears precisely as the pressure that changes “what has been said” into “what the utterance is to be received as.”
At the level of the perlocutionary act, this declaration produces awe, a reorientation of bearing, and an illumination of practice. The one-beat suspension created by the third line’s cutting function places the sword’s manifestation within an interval of breath, then releases it in the resulting, enduring brightness of hikari hanateri (光り放てり). The pivot jewel / mitama transforms a material sword into a sword of numinous authority; the eastern sky transforms the horizon of battle into the renewal of dawn. The perlocutionary work performed here is to loosen within the listening body the response that “a sword is something used to cut,” and to engender in its place the ethic that “a sword is something that comes forth in order to illuminate.” Not annihilation, but harmonization and beautification; not attack, but illumination—the sacred sword of Dōka 136 has come forth into the world and continues still to cast its light across the eastern heavens.
Coda
The sacred sword of Dōka 136 is not enclosed within its scabbard as a relic belonging only to a completed mythic past. In Susanoo no / tama no tsurugi wa (すさの男の／玉の剣は), numinous authority is gathered from the divine name into the jewel-sword. Through yo ni idete (世にいでて), it manifests at the threshold of world and night. Through higashi no sora ni / hikari hanateri (東の空に／光り放てり), it becomes established as the work of dawn. Grammatically, the poem reaches closure in the auxiliary ri (り); aspectually, however, that completion-and-continuance does not close the light. The utterance ends, but the radiance already cast forth continues across the eastern heavens.
The transformation enacted here is not an abandonment of the sword’s power. Susanoo’s fierce numinous authority is not erased; it is joined anew, turning from a power that severs another into a power that opens night toward dawn. Hanatsu (放つ), “to release” or “cast forth,” passes beyond the semantic field of the strike and becomes the verb through which light, voice, breath, and ki are sent from the body into the world. The jewel-sword therefore remains a sword even as it exceeds weaponhood. Rather than treating the other as a darkness to be eliminated, it changes the field in which self and other stand into something that can be seen. Fierce power is not pacified into absence; it manifests correctly as illumination.
Following the completion declared in Dōka 133, the tempering, purification, and bodily transformation of 134, and the musubi of true vacuum and emptiness in 135, Dōka 136 refuses to leave those attainments latent. It brings them “forth into the world.” What has been tempered within the body as dōjō, received by the heart-mind as learner, and joined into one beat of voice, breath, and body is released into the eastern heavens as technique. “East” is therefore more than a geographical direction. It is the direction in which practice can always begin again. “Supreme love” becomes the North Star that determines for whose sake the light is released and what life its manifestation is to sustain.
The drawing of the sword demanded by this poem is consequently not the decision to divide the world into victor and vanquished. It is the decision by which the world is folded from night toward morning. To bring the sacred sword forth is not to display proof of victory, but to transform one’s movement into a brightness sufficient to sustain both oneself and another. Susanoo’s jewel-sword did not illuminate the eastern sky only once in a remote age of the kami. Whenever practice is rightly undertaken, it is drawn forth again here and now, revealing the way without cutting. That unceasing radiance is the aftertone of hikari hanateri (光り放てり): the poem closes, yet the sacred sword continues to cast its light.
