解説
このページの第110首「天地に気結びなして中に立ち心構えは山彦の道」は、まず冒頭の「天地に」であめつち＝宇宙ぜんたいをフレームに据え、その天地と「気結びなして」――氣の結びを為して――と続けることで、単なる自分の気合いではなく、宇宙スケールの生起プロセスに自分を結び入れることを指しています。「結び」は日常語の「くくる」を越えて、神道で言う産巣日（むすひ）＝生成・生み出しの力にも触れる語であり、「気結び」は天地と自分のあいだに生命の筋を通すような働きを含むと注釈で整理されていました。そこからの「中に立ち」は、しばしば「丹田一点にセンターを取る」と狭く読まれがちですが、このページでは明確に“点ではない中”だと釘をさしています──すなわち、天地と気結びされた広がりとしての場（からだ全体という水の平面／大海原）の「まんなかに在る」ことであって、針先のような一点集中ではない、と（先行する道歌全体と整合する読みとして）注意が添えられているわけです。
この一首は、植芝盛平の六つのプライマーをとてもコンパクトに束ね直しています。プライマーの第一原理〈武＝宇宙原理〉は「天地に」の一語で呼び出され、武とは天地＝宇宙の運行そのものと結び合う働きだと再確認される。プライマーの第三原理〈心魂一如〉は、「気結びなして中に立ち」という連なりを通じて、気（いのちの結び）と身体の立ち方、心の居場所がズレなく一つになる状態として描かれる。プライマーの第五原理〈体＝道場、心＝修業者／修行者／学び手〉は、「中」が全身スケールの“水の場”としての中心だ、と読むことで、体ぜんたい＝天地の結び目がそのまま道場になる構図を支える。いっぽう後半の「心構えは山彦の道」は、プライマーの第二原理〈神や人との合気〉とプライマーの第四原理〈和合美化〉を受けて、心の構えは、山彦（やまびこ）のように“反発ではなく応答として響き返すスタイル”であるべきだと説く──つまり、ぶつからず、しかし空返事でもなく、神や相手や状況に応じて“こだま”のように調子を返す心構えこそが合気の Way だ、ということです。
直前の三首とも連なりがはっきり見えます。第107首は「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」と、光の神が天から降り立ち、海の底までかがやきを満たすタテ軸を描きました。第108首は「やみを照らして降りたちぬ大海原はよろこびの声」で、その光が闇を照らし、大海原＝世界全体／からだ全体の水の平面がよろこびの声を上げる、というヨコの広がりを歌った。第109首は「天照すいづ輝くこの中に八大力王の雄叫びやせん」で、その光がこの身まるごとの海原の中に満ち、その全水面が雄叫びとなって立ち上がるビジョンでした。そこから続く第110首の「天地に気結びなして中に立ち」は、まさにその光満ちた“中”＝身体全体の海原のあいだに立つことの説明であり、「心構えは山彦の道」は、第108首の「よろこびの声」と第109首の「雄叫び」を、今度はこだまの道＝応答としての声・技へとチューニングし直す言葉だと言えます。つまり──天地と気結びされた大海原としての身体の“中に立ち”、山彦のように響き返す心で世界と応答し合う。それが、六つのプライマーと光の三首（第107~109首）を受けた、このページの合気のまとめ方なのだと思います。
口語要約のひとこと
「天地と気を結びあわせて広がる「中」に立ち、心構えは山びこの道とせよ。」
和歌的修辞の補説――「中」に立ち、音として返る山彦
この一首には、すでに注釈した掛詞・体言止め・余韻に加えて、語の意味を歌の配置そのものに実演させる「位置の修辞」が働いています。五句の中央にあたる第三句へ「中に立ち」が置かれているだけではありません。三十一音を一モーラずつ数えると、「中に」が第十三音から第十五音を占め、その直後、一首全体の中央である第十六音から「立ち」が始まる。つまりこの歌は、中心に立つことを内容として告げると同時に、歌型のまんなかで実際に「立ち」始める構造になっています。もちろん、これは「中」を丹田の一点へ縮める読みではありません。むしろ、天地へひらかれた広がりの「中」に立つ動作を、三十一音の構造そのものへ写した、配置による見立て――いわば図像的な構成です。
音の面では、奇数句を貫く「ち」の縦糸が見逃せません。第一句の「天地（あめつち）」、第三句の「立ち」、第五句の「道（みち）」には、それぞれ「つち―たち―みち」という音の照応があり、とくに第三句と結句はともに「ち」で閉じています。これを厳密な脚韻と断定する必要はないものの、少なくとも脚韻的な反響であり、結句に現れる「山彦」は、それ以前からすでに音として歌の内部を往復していたことになります。さらに「天地に」と「中に」は、ともに〈名詞＋格助詞「に」〉という形で呼応する。宇宙ぜんたいという場と、その場のただ中という位置とが、同じ「に」によって入れ子にされるため、「山彦の道」は最後に説明されるより先に、「に……に」「つち―たち―みち」という調べとして聞かされているわけです。
語彙の配置には、少なくとも二本の縁語的な鎖が編み込まれています。一方には「天地―気―結び」という宇宙論的・生成的な語群があり、もう一方には「中―立ち―構え―道」という位置・身体・武の語群がある。第二句の「気結び」と第四句の「心構え」は、中央の「中に立ち」を挟む二つの七音句に置かれ、外との結合と内なる姿勢とを対句的に照らし合わせます。そして「立ち」は、天地のあいだに身体を置く語であると同時に、構えへつながる武術語でもあるため、二つの語群を結ぶ蝶番となる。縁語とは、意味上関係する語が離れた位置で互いを照応させる修辞ですが、この歌では語が「結び」を説明するだけでなく、語彙どうしが実際に結び合って一首を組み立てています。
ここでもう一つ、断定ではなく「影の掛詞」として拾えるのが、「中（なか）」と「仲（なか）」の同音です。表記された「中に立ち」は、第一義には天地のあいだ、その広がりのただ中に立つことを指します。しかし音だけを聞けば、「仲立ち」「中立ち」――二者のあいだに立って関係を取り持ち、結ばせること――の語群もかすかに立ち上がる。「中に立ち」は、それゆえ空間的な中心に在るだけでなく、天地、自他、打つものと受けるもの、発する力と返る力との「あいだを取り持つ」ことまで響かせます。正格の掛詞は、一つの音に二つの意味を担わせるものですが、ここでは本文の漢字表記だけから作者の意図を確定するよりも、「仲立ち」を呼び込む潜在的な同音照応として扱うのが適切でしょう。
統語上では、「なして」から「立ち」への運びにも独特の呼吸があります。「気結びなして」は接続助詞「て」によって先へ送られ、続く「立ち」は連用形のまま一度息を止め、第四句へ渡される。これは、用言を連用形でいったん中止しながら後続部分へつなぐ連用中止法に近い働きです。したがって第三句末は、明示的な切れ字によって断ち切る強い切れではなく、立ちながら次の呼吸を待つ「やわらかな切れ」となる。各句の境界はおおむね文節の境界とも一致しているため、典型的な句跨りと呼ぶより、句ごとの自立を保ったまま統語だけが流れ続ける構成と見るほうがよいでしょう。
その流れを第四句の係助詞「は」が転調させます。「天地に／気結びなして／中に立ち」までは、何を為し、どこに立つかという生成の過程である。ところが「心構えは」と題目が提示された瞬間、歌は動作の連鎖から、道歌としての定義・教示へ折れ返ります。「は」は判断の主題を掲げ、ときに対照的に取り立てる係助詞であり、ここでは外形の「立ち」から内面の「構え」へ照準を移す蝶番です。ただし、狭義の係り結びを起こす「ぞ・なむ・や・か・こそ」も、それに呼応する特別な結びの活用形もないため、これを係り結びそのものとする必要はありません。「は」による主題化と転調こそが中心です。
また上三句は、下句の「心構え」を導く、序詞的な前置きとしても働いています。序詞は本来、音や意味の連想を用いて特定の語句を導く長い修辞ですが、この歌の上三句は、ある一語を技巧的に呼び出すというより、下句の判断が成立する宇宙的条件を先に整えています。したがって、これを定型的な序詞と断定するより、「天地と気結びし、その中に立つ」という意味の連続によって「心構え」を導く、有心の序に近い序詞的展開と見るのが穏当です。上の句は単なる飾りではなく、下の句の教えを成立させるための祭場そのものを先に設けているのです。
主体の省略も、この道歌の力を支えています。「我」も「汝」も、「誰が立つのか」を限定する代名詞も置かれていない。そのため、「中に立ち」の主体は盛平個人に閉じず、この歌を唱え、読み、技として受ける位置へ開かれます。同様に「心構えは山彦の道」の末尾には、文法上補い得る「なり」「である」が書かれていません。すでに指摘された体言止めに、主語と断定辞の省略が重なることで、この一句は個人的な感想ではなく、話者を越えて成立する箴言のような響きを帯びます。命令形を使わず、それでも「かく立て、かく構えよ」と働きかける力は、この人称の空所から生じています。
「山彦の道」には、見立て・隠喩・擬人法も重なります。山彦を「山彦のような応答」と説明するのではなく、山彦そのものに一つの「道」があると言い切ることで、反響という自然現象が、歩み、教え、修行の型を持つ存在として立ち上がる。しかも山彦は自然の反響であると同時に山の霊的存在でもあるため、これは単なる擬人化と神話的な実在感との境を往復します。「道」もまた、山中を通る具体的な路と、合気を修める武道・神道的な Way とを同時に保つ一語多義です。これは同音異義による正格の掛詞ではありませんが、具象的な山道と抽象的な修行道を一語の内部で重ね、結句の余韻を二方向へ開いています。
一首ぜんたいを眺めれば、「天地」という最大の広がりから、「気結び」という関係の働きへ入り、「中に立ち」で中心を通り、「心構え」という内面へ収束し、最後に「山彦の道」として再び世界へ響き出してゆく、収縮と再拡張の構図も見えてきます。第一句と第五句は自然・世界の大景として首尾照応し、第二句と第四句は「気結び／心構え」という二つの複合語として中央句を挟む。そこに第三句の「中に立ち」が軸として置かれるため、一首は同心円的、あるいは環状的な構成を取ります。第二句の「結び」は、天地と氣を結ぶという内容語であるばかりでなく、離れた句、音、意味を結び合わせる一首自身の制作原理をも言い当てている。つまりこの歌は、気結びと山彦の道について説明するだけではありません。語の配置によって「中」に立ち、縁語によって結び、音によって響き返すことで、詠んでいる道を歌の形式そのものとして実演しているのです。
なお、分類を増やすためだけに修辞名を当てはめることは避けるべきでしょう。「天地」は古典的な歌語ではあっても特定の語へ固定的に掛かる枕詞ではなく、「山彦」も通常の意味で特定の名所・旧跡を示す歌枕ではありません。また、典拠となる古歌の句や趣向が特定されないかぎり、本歌取りとも断定できない。この一首の技巧は、枕詞・歌枕・係り結びを数多く備えることではなく、中央配置、音の照応、縁語の交差、潜在的な「中／仲」、連用中止、主題化、省略、そして首尾の反響を、ひとつの「気結び」として束ねているところにあります。
発話行為理論
オースティン（Austin, 1962）の発話行為論に引きつけるなら、この一首の発話行為（locutionary）は、単に「天地と気を結び、中心に立つ」という内容を告げるだけではない。「天地に／気結びなして／中に立ち」という連用の鎖と、「心構えは／山彦の道」という名詞的着地が、上の句・下の句の折りを形づくり、第一・二句が第四句へ、第三句が第五句へと照り返す。ここで重要なのは、露骨な命令文法よりも、第三句末の「立ち」がつくる切れである――厳密には俳句的な切れ字そのものというより、連用形が一度息を切りつつ下の句へ橋を架ける、句切れとしての働きが前面に出ている。したがって、この歌の locution は、語義・音価・文法・掛詞の重なりをふくんだ「言い方そのもの」に宿る。
そのうえで発話内行為（illocutionary）の力点は、記述よりも教示にある。「心構えは山彦の道」は表面上は定義文だが、道歌という場では、「かく構えよ」「反発ではなく応答として働け」という規範の力を帯びる。第一・二句の天地的な結びが第四句の心構えへ折り返されるため、外なる宇宙秩序がそのまま内なる構えの規準へと転写されるからである。さらに「結び」は、単なる結束ではなく産霊の生成力をも帯び、「山彦」は衝突の比喩ではなく、返り、響き、応じる運動の像を運ぶ。その結果、この一首は命令形を用いずに命じる――合気の構えを、中心性と共鳴性の一致として打ち出す。
発話媒介行為（perlocutionary）として期待されるのは、意味理解を越えて心身の向きを変えることである。下の句が上の句をこだまのように返すため、「山彦の道」は観念として説明される前に、形式として先に経験される。第一・二句が第四句へ返り、第三句が第五句へ返る反照は、この歌が主題化する「山彦」を歌の内部で実演してしまう。読後に残る余韻は、ぶつかる心をほどき、「中に立ち」を一点集中ではない天地のあいだの中として感じさせ、技の方向を反発から応答へ、競り合いから和合へと静かにずらしてゆく――そこに、この一首の語媒介行為の中核がある。
コーダ
この一首が最後に残すのは、「中心」と「応答」を別々の教えとして理解してはならない、ということでしょう。天地と気結びして立つ「中」は、あらかじめ所有できる固定点ではありません。それは、天と地、自と他、発するものと返るものが、そのつど結ばれることによって現れる関係の場です。したがって「心構え」も、自己を硬く囲って守る構えではない。その場を通る氣の筋を損なわず、来たものをそのまま反射するのでも、内へ呑み込むのでもなく、天地へ通し、その全体にふさわしい響きへ変えて返す構えとなります。山彦は模倣ではありません。山の形、距離、空気を受け、同じ声を、もはや同一ではない声として返す。その返りに生じる差こそが、合気の働きです。
「気結び」と「山彦の道」は、ゆえに上の句と下の句へ分かれた二つの主題ではなく、一つの運動の往路と復路です。天地と結ばれて「中」に立つことが往路なら、心を山彦として世界へ返すことが復路であり、その往復が絶えず新しい「中」を生み直す。技は、中心から一方的に放たれるものではありません。結びによって生じた場が技を生み、その技の返りが、また場を結び直します。ここでの「立つ」は停止することではなく、響きが行き来できるように場を保つことなのです。
だからこの道歌は、読む者に一点へ凝固せよとは告げません。天地へひらかれ、全身を大海原として保ち、その広がりのなかで、相手、出来事、声、力が、どのように返るべきかを聴け、と促しています。そうして読まれるとき、「心構えは山彦の道」という体言止めは、結論ではなく入口となる。道は歌の末尾で閉じず、読む者の身体へ移り、次の呼吸、次の一歩、次の応答として続いてゆきます。気結びとは、その続きを可能にするよう天地と自己を結ぶこと。そして山彦の道とは、その結びを世界へ返しながら、絶えず新しく生かし直すことなのです。

Commentary
Dōka 110 on this page, Ametsuchi ni / ki musubi nashite / naka ni tachi / kokorogamae wa / yamabiko no michi (天地に／気結びなして／中に立ち／心構えは／山彦の道), first establishes ametsuchi (天地)—the entire cosmos—as its frame through the opening phrase ametsuchi ni (天地に). It then continues with ki musubi nashite (気結びなして)—“forming a joining of ki”—thereby pointing not to a merely personal exertion of spirit, but to the act of joining oneself into a cosmically scaled process of arising. Musubi (結び) reaches beyond the everyday sense of tying or fastening. It also touches upon the Shintō idea of musuhi (産巣日), the generative power by which things arise and are brought forth. The annotations accordingly described ki musubi (気結び) as including an operation something like running a living sinew between heaven-and-earth and oneself. From there, naka ni tachi (中に立ち) is often read too narrowly as “taking one’s center at a single point in the tanden.” This page, however, explicitly insists upon a “middle that is not a point.” It means being in the midst of a field opened through the joining of ki with heaven and earth—the water-plane or great ocean of the whole body—not concentrating upon a point as narrow as the tip of a needle. This caution is offered as a reading consistent with the preceding sequence of dōka as a whole.
This single poem very compactly gathers Ueshiba Morihei’s Six Primers back together. The First Principle, “Bu = Cosmic Principle,” is called forth by the single expression ametsuchi ni (天地に), reaffirming that bu is the operation of joining with the movement of heaven-and-earth—the cosmos itself. The Third Principle, “Heart-mind and Spirit, Inseparable,” is expressed through the sequence ki musubi nashite naka ni tachi (気結びなして中に立ち): the joining of life called ki, the manner in which the body stands, and the place in which the heart-mind abides all become one without displacement. The Fifth Principle, “Body = Dōjō; Heart-Mind = Practitioner / Ascetic / Learner,” is supported by reading the naka (中), the “middle,” as the center of a whole-body-scale field of water. The entire body—the very knot at which heaven and earth are joined—thereby becomes the dōjō. The latter half, kokorogamae wa yamabiko no michi (心構えは山彦の道), receives the Second Principle, “Aiki with Kami / Another / Others,” and the Fourth Principle, “Harmonious Beautification,” and teaches that the disposition of the heart should be a style of sounding back like yamabiko (山彦): not resistance, but response. In other words, the way of aiki lies in a heart-mind that does not collide yet does not return an empty answer either; it responds to the kami, other(s), and to situation(s) by returning the appropriate tone like an echo.
Its continuity with the preceding three poems is readily visible. 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), described a vertical axis along which the deity of light descends from heaven and fills even the depths of the sea with radiance. Dōka 108, Yami o terashite oritachinu / ōunabara wa yorokobi no koe (やみを照らして降りたちぬ／大海原はよろこびの声), sang of that light illuminating the darkness, while the great ocean—the whole world, or the water-plane of the whole body—raises a voice of joy in horizontal expansion. Dōka 109, Ama terasu / izu kagayaku / kono naka ni / hachidairikiō no / otakebi ya sen (天照す／いづ輝く／この中に／八大力王の／雄叫びやせん), presented a vision in which that light fills the ocean of this entire body, and the whole water-plane rises as a mighty cry. Dōka 110 then continues with ametsuchi ni ki musubi nashite naka ni tachi (天地に気結びなして中に立ち), explaining precisely what it is to stand within that light-filled naka (中)—the ocean of the whole body. Its closing phrase, kokorogamae wa yamabiko no michi (心構えは山彦の道), retunes the “voice of joy” in Dōka 108 and the “mighty cry” in Dōka 109 into the way of the echo: voice and technique as response. That is to say: stand within the “middle” of the body as a great ocean joined through ki with heaven and earth, and answer the world with a heart that sounds back like yamabiko. This is how the present page gathers aiki together after receiving both the Six Primers and the three poems of light, Dōka 107–109.
One-sentence colloquial summary
“Join ki with heaven and earth, stand within the expansive ‘middle,’ and let the disposition of the heart be the way of the mountain echo.”
Supplement on waka rhetoric: Standing in the “middle,” returning as sound: yamabiko
In addition to the kakekotoba (掛詞), taigendome (体言止め), and yoin (余韻) already discussed in the annotations, this poem employs a “rhetoric of placement” in which the arrangement of the poem itself performs the meanings of its words. It is not merely that naka ni tachi (中に立ち) appears in the third line, the center of the five-line form. When the thirty-one morae are counted one by one, naka ni (中に) occupies the thirteenth through fifteenth morae, while tachi (立ち) begins immediately afterward, at the sixteenth mora—the exact center of the poem. Thus, while the poem declares the act of standing at the center, it also actually begins to “stand” at the center of its poetic form. This, of course, does not reduce the “middle” to a single point in the tanden. Rather, it transfers the act of standing within a spacious naka opened toward heaven and earth into the very structure of the thirty-one morae. It is a mitate through placement—a kind of iconic composition.
On the level of sound, the vertical warp-thread of chi (ち) running through the odd-numbered lines should not be overlooked. Ametsuchi (天地) in the first line, tachi (立ち) in the third, and michi (道) in the fifth produce the phonetic correspondence tsuchi–tachi–michi (つち―たち―みち). The third and closing lines, in particular, both end in chi. There is no need to declare this a strict end rhyme, but it is at least a rhyme-like reverberation. The yamabiko that appears in the closing line has therefore already been traveling back and forth inside the poem as sound. Moreover, ametsuchi ni (天地に) and naka ni (中に) share the same grammatical form: noun plus the case particle ni (に). The field of the entire cosmos and the position within the midst of that field are nested within one another by the same ni. Consequently, before yamabiko no michi (山彦の道) is explained at the end, it has already been made audible as the rhythms ni … ni (に……に) and tsuchi–tachi–michi (つち―たち―みち).
At least two chains of engo (縁語), or semantically associated diction, are woven into the placement of the vocabulary. One is the cosmological and generative cluster ametsuchi–ki–musubi (天地―気―結び). The other is the spatial, bodily, and martial cluster naka–tachi–kamae–michi (中―立ち―構え―道). The seven-mora second and fourth lines, ki musubi (気結び) and kokorogamae (心構え), stand on either side of the central naka ni tachi (中に立ち), bringing outer conjunction and inner disposition into a quasi-parallel correspondence. Tachi (立ち), moreover, means placing the body between heaven and earth, while also belonging to the martial vocabulary of stance and preparedness. It therefore serves as the hinge joining the two lexical clusters. Engo is a rhetorical operation in which semantically related words illuminate one another from separated positions. Here, however, the words do not merely explain “joining”; the vocabulary itself actually joins together to construct the poem.
Another possibility, best treated not as a firm assertion but as a “shadow kakekotoba,” lies in the homophony of naka (中), “middle,” and naka (仲), “relationship” or “interpersonal bond.” In its written form, naka ni tachi (中に立ち) primarily means standing between heaven and earth, within the midst of that expanse. Yet when heard only as sound, it faintly calls forth the lexical cluster of naka-dachi (仲立ち), mediation, and naka-dachi (中立ち), standing in the middle: standing between two parties, tending their relationship, and bringing them into conjunction. Naka ni tachi therefore reverberates not only as being spatially centered, but also as mediating between heaven and earth, self and other, the one who strikes and the one who receives, the force sent forth and the force returned. A strict kakekotoba makes a single sound bear two meanings. Here, however, rather than determining authorial intent from the written character alone, it is more appropriate to regard this as a latent homophonic correspondence that summons the sense of mediation contained in nakadachi (仲立ち).
Syntactically, the movement from nashite (なして) to tachi (立ち) also possesses a distinctive breath. Ki musubi nashite (気結びなして) is carried forward by the connective particle te (て), while the following tachi remains in the continuative form, momentarily suspending the breath before passing into the fourth line. This operates much like ren’yō chūshihō (連用中止法), the continuative suspension by which a predicate pauses in its continuative form while remaining connected to what follows. The end of the third line therefore does not present the hard cut of an explicit kireji (切れ字). It is instead a “soft cut” that stands while awaiting the next breath. Because the boundaries of the lines generally correspond to the boundaries of syntactic phrases, it is more accurate to describe the poem as allowing its syntax to continue while preserving the relative independence of each line, rather than calling it a typical case of ku-matagari (句跨り), or syntactic overflow across line boundaries.
The topic particle wa (は) in the fourth line retunes that continuing movement. Up through ametsuchi ni / ki musubi nashite / naka ni tachi (天地に／気結びなして／中に立ち), the poem has unfolded as a generative process: what is to be done, and where one is to stand. The moment kokorogamae wa (心構えは) presents the disposition of the heart as its topic, however, the poem folds back from a chain of actions into definition and instruction as a dōka. Wa establishes the topic of judgment and may also mark a contrast; here, it serves as the hinge that shifts the poem’s focus from the outward act of standing to the inward condition of preparedness. Strictly speaking, however, the poem contains none of the particles that produce classical kakari-musubi (係り結び)—zo (ぞ), namu (なむ), ya (や), ka (か), or koso (こそ)—nor any specially inflected concluding form corresponding to them. There is therefore no need to classify this as kakari-musubi itself. The essential operation is the topicalization and tonal turn created by wa.
The upper three lines also function as a prelude resembling a jo-kotoba (序詞), guiding the poem toward the phrase kokorogamae (心構え) in the lower verse. In its classical form, a jo-kotoba is an extended rhetorical preface that uses phonetic or semantic association to introduce a particular word or phrase. Here, however, the first three lines do not cleverly summon a single word. Instead, they first establish the cosmological conditions under which the judgment of the lower verse can become valid. It is therefore more measured to regard the passage not as a fixed-form jo-kotoba, but as a jo-like development close to an ushin no jo (有心の序): a semantically continuous preface in which “joining ki with heaven and earth and standing within its midst” leads into the disposition of the heart. The upper verse is not an ornament. It first constructs the ritual ground upon which the teaching of the lower verse can stand.
The omission of an explicit subject also sustains the force of this dōka. Neither ware (我), “I,” nor nanji (汝), “thou,” appears; no pronoun limits who it is that stands. The subject of naka ni tachi (中に立ち) is therefore not enclosed within Morihei as an individual. It remains open to the position of whoever recites the poem, reads it, or receives it bodily as technique. Likewise, the grammatical ending that might be supplied after kokorogamae wa yamabiko no michi (心構えは山彦の道)—nari (なり) or de aru (である)—is left unwritten. The already-noted taigendome is thus joined by the omission of both subject and copula. As a result, the line resonates not as a private observation, but as an aphorism whose validity exceeds its speaker. The poem never employs an imperative form, yet it still acts as though saying, “Stand in this way; take up the heart-mind in this way.” That force arises from the open space left by grammatical person.
Within yamabiko no michi (山彦の道), mitate, metaphor, and personification overlap. Rather than explaining the phrase as “a response resembling a mountain echo,” the poem declares that yamabiko itself possesses a “way.” The natural phenomenon of reverberation thereby takes shape as an entity with a path to walk, a teaching to embody, and a form of practice to follow. Moreover, yamabiko is both a natural echo and a numinous being of the mountains. The phrase therefore travels back and forth across the boundary between simple personification and mythic presence. Michi (道), too, preserves more than one sense at once: the concrete path passing through the mountains, and the martial or Shintō way through which aiki is cultivated. This is not a strict kakekotoba founded on homophonic difference, but it layers a concrete mountain path and an abstract path of practice within a single word, opening the resonance of the closing line in two directions.
Viewed as a whole, the poem also displays a pattern of contraction and re-expansion. It begins with the maximal expanse of ametsuchi (天地), enters the relational operation of ki musubi (気結び), passes through the center at naka ni tachi (中に立ち), contracts inward toward kokorogamae (心構え), and then sounds outward into the world once again as yamabiko no michi (山彦の道). The first and fifth lines correspond as vast scenes of nature and world, while the second and fourth lines flank the central line as the two compound expressions ki musubi and kokorogamae. With naka ni tachi placed as the axis in the third line, the poem assumes a concentric or ring-like construction. The musubi of the second line is therefore not merely a word describing the joining of heaven, earth, and ki. It also names the poem’s own principle of composition, by which separated lines, sounds, and meanings are joined. This poem does not merely explain ki musubi and the way of yamabiko. Through the placement of its words, it stands within its own “middle”; through engo, it joins; and through sound, it echoes back. The poetic form itself performs the way it sings.
Care should nevertheless be taken not to apply rhetorical labels merely for the sake of multiplying classifications. Ametsuchi (天地) is classical poetic diction, but it is not a makurakotoba (枕詞) conventionally attached to a fixed succeeding word. Nor is yamabiko ordinarily an utamakura (歌枕) naming a particular celebrated place or historical site. Likewise, unless a source poem with a specifically identifiable phrase or conception can be established, the poem should not be classified as honkadori (本歌取り). Its craftsmanship does not lie in possessing a great number of makurakotoba, utamakura, or instances of kakari-musubi. It lies in gathering central placement, phonetic correspondence, intersecting chains of engo, the latent resonance of naka (中) and naka (仲), continuative suspension, topicalization, omission, and beginning-to-end reverberation into a single act of ki musubi.
Speech Act Theory
Viewed through Austin’s (1962) theory of speech acts, the locutionary act of this poem does not consist merely in stating the content, “Join ki with heaven and earth and stand at the center.” The continuative chain ametsuchi ni / ki musubi nashite / naka ni tachi (天地に／気結びなして／中に立ち), followed by the nominal landing kokorogamae wa / yamabiko no michi (心構えは／山彦の道), forms the fold between the kami-no-ku (上の句), the upper verse, and the shimo-no-ku (下の句), the lower verse. The first and second lines reflect into the fourth, while the third reflects into the fifth. What matters here is less an overt imperative grammar than the cut created by tachi (立ち) at the end of the third line. Strictly speaking, this is not itself a haiku-like kireji. Rather, the continuative form briefly interrupts the breath while simultaneously laying a bridge into the lower verse. The poem’s locution therefore resides in the manner of saying itself—in the interwoven semantic values, sounds, grammar, and resonances of the kakekotoba.
The illocutionary force, in turn, lies more in instruction than description. On its surface, kokorogamae wa yamabiko no michi (心構えは山彦の道) is a definitional statement. Within the setting of a dōka, however, it acquires the normative force of “Take up the heart-mind in this way” and “Operate as response rather than resistance.” Because the cosmic joining of the first and second lines folds back into the disposition of the heart in the fourth, the outer order of the cosmos is transferred directly into the criterion governing inward preparedness. Moreover, musubi bears not merely the sense of fastening, but also the generative force of musuhi; yamabiko carries not an image of collision, but one of return, resonance, and responsive movement. The poem therefore commands without using an imperative form. It establishes the disposition of aiki as the coincidence of centeredness and resonance.
The perlocutionary effect sought by the poem is a transformation in the orientation of mind and body that exceeds mere intellectual understanding. Because the lower verse returns the upper verse like an echo, the way of yamabiko is experienced formally before it is explained conceptually. The first and second lines sound back into the fourth, while the third sounds back into the fifth; the poem thereby performs within itself the very yamabiko it makes its subject. The lingering yoin after the reading loosens the heart-mind that would collide. It allows naka ni tachi (中に立ち) to be felt not as concentration upon a single point, but as standing within the spacious middle between heaven and earth. It quietly shifts the direction of technique from resistance to response, and from contention to harmonious joining. Therein lies the core of this poem’s perlocutionary force.
Coda
What this poem finally leaves with us is the recognition that “center” and “response” must not be understood as separate teachings. The naka (中), the “midst” in which one stands after forming ki musubi (気結び) with heaven and earth, is not a fixed point that can be possessed in advance. It is a relational field that appears each time heaven and earth, self and other, that which issues forth and that which returns, are joined. The disposition of the heart-mind is therefore not a guard that hardens itself around the self. It is a readiness that does not damage the living line of ki passing through the field; it neither merely reflects what arrives nor swallows it inward, but carries it through heaven and earth and returns it as the resonance appropriate to the whole. A mountain echo is not imitation. It receives the mountain’s contours, distance, and air, and returns the same voice as a voice that is no longer identical. The difference arising in that return is precisely the operation of aiki.
Ki musubi (気結び) and yamabiko no michi (山彦の道) are therefore not two subjects divided between the upper and lower verses. They are the outward and returning passages of a single movement. If joining heaven and earth and standing within their midst is the outward passage, then allowing the heart-mind to return into the world as yamabiko is the returning passage. Their circulation continually brings forth a new “middle.” Technique is not projected unilaterally from a center. The field produced through joining gives birth to technique, and the return of technique binds the field anew. To “stand” here is not to become motionless. It is to sustain a field through which resonance can travel in both directions.
For this reason, the dōka does not tell its reader to congeal at a single point. It urges one to remain open to heaven and earth, to preserve the whole body as a great ocean plain, and, from within that expanse, to listen for how the other, the event, the voice, and the force are to return. Read in this way, the nominal ending kokorogamae wa yamabiko no michi (心構えは山彦の道), “the heart-mind’s disposition is the way of the mountain echo,” is not a conclusion but a threshold. The way does not close at the end of the poem. It passes into the reader’s body and continues as the next breath, the next step, and the next response. Ki musubi means joining heaven, earth, and oneself so that this continuation remains possible. Yamabiko no michi means returning that joining into the world and, through that return, continually bringing it to life anew.
