解説
このページの第15首は、原文「左右をば切るも払うも打ち捨てて人の心は直ぐに馳せ行け」を掲げて、「人の心（hito no kokoro）」を「感情でも知性でも単独ではない統合されたハート＝マインド」として明確に位置づける（批判的口語訳：「左右に斬る・払うといった手先の応酬は捨てて、「人の心」を一直線に、ただちに走らせよ」）。語の芯を押さえると、打ち捨てるは「思い切って捨てる・顧みない」の意、直ぐ／直ぐには「曲がらず（一直線）・ただちに」、馳せるは「速く走る／思いを至らせる」だから、手立て（左右の斬り払い）を見切って「心（統合的心身）」を一直線に、ためらわず送り出すという命が立ち上がる。
この読解を、植芝盛平の六つのプライマーの糸で束ね直すと構図が見える。プライマーの第一原理が示した〈武＝宇宙原理〉を背骨に、プライマーの第二原理の〈神や人との合気〉を「心の運用」へ落とし、プライマーの第三原理の〈心魂一如〉でブレのない芯を作る。プライマーの第四原理の〈和合美化〉は“どの方向に心を走らせるか”のテロスを与え、プライマーの第五原理の〈体＝道場、心＝修業者／修行者／学び手〉で日常の最小単位まで徹底し、プライマーの第六原理の〈「至愛」の源に順う〉が最上位の拠り所になる。その総決算として第15首は、左右（テクニックの分岐）に心を迷わせるな／ただちに一直線に「心（heart‑mind）」を前へ送れと、運用のベクトルを一本に収斂させる。
さらに直前三首の運びを糸足しすると、第12首の「天地の息にまかせつつ」が「直ぐに」の拍（リズム）を与え、第13首の「清眼」が一直線の見極めを磨き、第14首の「前ぞ見えたり」が眼前の課題に心を出す姿勢を固めた。だから第15首は、息（第12首）×眼（第13首）×眼前（第14首）の整えを前提に、左右の手筋（cut／parry）をいったん置き、「心そのもの」を先に送る——技より先に関係と意志（heart‑mind）を通すという合気の作法を、短句で叩き込む章だと言える。
口語要約のひとこと
「左右への斬りや払いは捨てて、人の心はまっすぐに駆けて行け。」
和歌修辞の補遺――「左右」から「直ぐ」へ
この首でなお名指されるべき修辞の核は、上の句が単に技法を並べ、下の句が心を説くという二段構成ではなく、二項を一項へ、横方向の分岐を一本の前進軸へ、外物を操作する他動性を心自身の発動へと収斂させる構えにある。音数は「さ・ゆ・う・を・ば／き・る・も・は・ら・う・も／う・ち・す・て・て／ひ・と・の・こ・こ・ろ・は／す・ぐ・に・は・せ・ゆ・け」と過不足なく五七五七七に収まり、上の句十七音には左右・切る・払ふという分岐が詰め込まれるのに対し、下の句十四音は「人の心」という一つの主題と「馳せ行け」という一つの方向へ絞られる。定型そのものが、複数の選択肢を一筋の運動へ圧縮する器になっている。
初句「左右」は、対義的な二語を一つの熟語に畳み込む対語であると同時に、両端を挙げることでそのあいだの全域を表す両極列挙として働く。そこへ第二句の「切るも払ふも」が係助詞「も」を反復し、切るか払うかという二者択一だけでなく、その種の技法選択をことごとく包摂する。左右・切る・払ふは、個別の方向と手法を示しながら、同時に技法体系全体を代理する提喩となるのである。「左右をば」の「をば」と「人の心は」の「は」も照応し、前者では捨てられる対象を、後者では走り出す主体を焦点化する。狭義の係り結びを成立させる「ぞ・なむ・や・か・こそ」と特別な結びは置かれていないため、ここは係り結びというより、「をば／も……も／は」による焦点化と並列の呼応として読む方が精密である。
第三句「打ち捨てて」には、さらに巧妙な聴覚上の折り返しがある。「切る」「払ふ」と武技動詞が続いたため、耳は「打ち」を第三の技――切る・払う・打つ――として一瞬受け取る。ところが「捨てて」まで聞いたところで、「打ち」は独立した打撃動詞ではなく、複合動詞「打ち捨つ」の接頭的成分として再分節される。すなわち、技の列挙を続けるはずだった「打ち」が、その技の列そのものを捨てる語へ反転する。これは正統的な同音異義の掛詞ではないが、先行文脈によって語の切り分けを一時的に揺らす、掛詞的な聴覚の綾といえる。「捨てて」の「て・て」という同音反復も、文法上は後続句へ開きながら、音の上では小刻みな切断を響かせる。歌は「技を捨てよ」と説明する前に、技として聞こえた「打ち」を、耳のなかで捨てる語へ変えてみせるのである。
この点から見ると、既注の「三句切れ」は、完全に文が閉じる厳密な句切れというより、「三句目に置かれた意味上の折れ」あるいは「三句切れ的な転調」と呼ぶ方がよい。「打ち捨てて」の接続助詞「て」は、下の句の主命令「馳せ行け」に連用的に接続しており、第三句末に句点を置いて文を完結させることはできない。したがって、文法は切れずに流れ続けながら、意味と主体だけが、外の技法から内なる心へ大きく切り替わる。句切れが文や意味の完結点を基準とすることに照らせば、この首の要所は「切断」よりも、連続のただなかに生じる折れである。 また、語そのものが五音・七音の境をまたぐ狭義の句跨がりではなく、各句の文節を保ったまま統語的な係り受けを次句へ送り出す構造になっている。「左右をば」は次句の動詞を待ち、「人の心は」は結句の述語を待つ。その待機が、歌全体を最後の「行け」まで停止させない。
語彙の連鎖にも、複数の縁語的語群が重なっている。第一は「左右―切る―払ふ―打ち」という武技と方向の語群、第二は「祓ふ―捨つ―心―直ぐ」という浄化と矯正の語群、第三は「直ぐ―馳す―行く」という道行きと運動の語群である。もっとも、古典和歌における縁語は、単に意味が近い語を寄せ集めれば成立するわけではなく、慣用的・伝統的な連想関係をどこまで認めるかについて明確な境界を引きにくい。ゆえに、この首では厳格な意味での縁語と断定するより、「縁語的な意味場」あるいは「連想語群」として扱うのが穏当である。掛詞が周囲の縁語群によって二つの文脈を支えられるという和歌修辞の構造から見ても、「払ふ／祓ふ」は孤立した語呂合わせではなく、捨てる・心を直す・まっすぐ進むという周辺語に支えられて宗教的な意味を立ち上げる。
「直ぐ」もまた、すでに語義として示されている「まっすぐ」と「ただちに」を、一つの発動のなかで同時に働かせる一語両義である。これは異なる表記を重ねる典型的掛詞ではないが、空間的直進と時間的即時性を同時に命令する意味掛けになっている。初句の「左右」が横方向の二極を開くのに対して、結句直前の「直ぐ」はその横軸を消し、一つの直線へ組み替える。前という語は明示されていないにもかかわらず、「左右」を捨てたのちに「行け」と命じるため、残された方向はおのずから前方として立ち上がる。この方位の対照法によって、左右という平面的な選択肢は、直ぐという軸線へ変換される。
「人の心は／直ぐに馳せ行け」には、擬人法と見立てがいっそう鮮明に働く。通常の「心を馳せる」では、人が心や思いを遠方へ及ぼすが、ここでは「心」が「は」によって主体化され、心そのものが馳せ、行く。慣用的には送られる側であった心が、自ら走る行為者へ反転するのである。「馳せ行け」は、速さや走法を表す「馳す」と、進行方向を示す「行く」を重ねた複合的な運動表現であり、心を走者、さらには明示されない駒として見立てる。上の句の「切る・払ふ・打ち捨つ」が対象に働きかける他動詞系列であるのに対し、結句は心自身が走り去る自動的運動へ移る。したがって、この歌の転換は単なる「技から精神へ」ではない。外界を切り分け、払い、処理しようとする主体が退き、心そのものに運動と方向を返す、行為主体の組み替えなのである。
結句は体言止めでも詠嘆止めでもなく、「行け」による命令形止めである。明示的な「や・かな・けり」などの切れの標識を用いず、最後の活用形そのものを発話の刃先とするため、歌は鑑賞の対象として静止せず、そのまま行為へ接続される。命令形は一首の文法を強く閉じる一方、「行く」という運動は歌の外へ継続するため、余韻は静かな残響ではなく、なお遠ざかり続ける運動として残る。また、定型的な枕詞・歌枕・本歌取りは見いだしにくく、上の句も、特定語を同音や比喩によって導く正式な序詞というより、下の句の命令を成立させる前提条件としての「序詞的前置」である。序詞を文脈転換と本旨への連結によって認定する立場に照らしても、この三句は本旨から切り離せる装飾ではなく、捨てる行為そのものとして命令内部に組み込まれている。
こうして第15首は、「左右に迷わず、まっすぐ行け」という教訓を外から説明する歌ではなくなる。左右という二極を掲げ、「も……も」で分岐を増幅し、「打ち」を武技から放下へ反転させ、他動詞の連鎖を心自身の走行へ渡し、最後の命令形によって読む口と身体を歌外へ送り出す。言葉が心の直進を描写するのではない。歌の文法と音そのものが、左右へ散ろうとする心を一線に畳み、「直ぐに馳せ行け」と発動させるのである。
発話行為理論
オースティン（Austin, 1962）の枠で見直すと、この第15首のまず発話行為（locutionary／ロキューション）は、左右・切る・払ふという技法語をまず提示し、三句切れの折り目で一度その系列を断ち、「人の心は」へ主題を移して「直ぐに馳せ行け」という命令へ流し込む、その言表内容そのものにある。とりわけ一・二句の「左右をば／切るも払ふも」と四句の「人の心は」とのあいだには、をば／は による焦点化の照応があり、三句の「打ち捨てて」と五句の「馳せ行け」とのあいだには、放下と駆動という運動の照応がある。この折り返しによって、歌面は「何を扱うか」から「どこへ向かわせるか」へと、技法の列挙から心のベクトルへと、語の重心をずらしている。さらに 払ふ／祓ふ の掛詞を立てるなら、捨てられるのは単なる手先の選択肢ではなく、反応としての濁りそのものになる。
したがって発語内行為発話内行為（illocutionary／イルロキューション）の中核は説明ではなく訓戒であり、しかも単なる速度命令ではない。「直ぐ」が「ただちに」と「まっすぐ」を重ねるため、フォースは時間的即時性と倫理的直心性を同時に帯びる。そこから発話媒介行為（perlocutionary／ペルロキューション）は、読む者・稽古する者の意識において、左右・切る／払ふの分岐へ貼りつく逡巡を削ぎ、心を一点に収斂させ、その一点を前へ走らせるところに現れる。要するにこの歌は、技を説く歌である以前に、迷いの運動を断ち、心の運動を起動する歌として働く。オースティンの言い方を借りれば、「言うことのなかで命じ」、「言うことによってまっすぐな発動を生じさせようとする」道歌である。
コーダ
「左右をば打ち捨てる」とは、左も右も、切ることも払ふことも、稽古から消し去ることではない。捨てられるのは、それらの分岐を「人の心」より先に立て、どの技を選ぶかという計算へ行為の根を預ける、その順序である。心が左右のあいだで停止すれば、技の選択肢は増えても、相手との関係は痩せてゆく。反対に、心を先へ送るなら、技はもはや主権者ではなく、その関係を通すために一瞬だけ結ばれる形として生まれ直す。
だから「直ぐ」は、頑なな直線でも、無思慮な突進でもない。第一原理から第六原理までを通して読むなら、それは武という宇宙原理に立ち、人との合気に開かれ、心魂一如に保たれ、和合美化へ向かい、身体の日常に鍛えられ、「至愛」の源に照らされる生きた軸である。ゆえに、その心は形の上ではいくらでも曲がり、応じ、転じながら、根においては曲がらない。「まっすぐ」とは、世界を一本の線へ押し込めることではなく、分岐する世界のただなかで、関係の根を失わないことである。
そして「打ち捨てて」の「て」は、捨てると言いながら文を閉じず、そのまま「馳せ行け」へ渡してゆく。歌は、左か右かの正解を与えるのではない。選択の再帰へ沈みかけた心の文法を、分岐から継続へ、処理から発動へと組み替える。命令形を声にした瞬間、読者はもはや命令を眺める者ではなく、その命によって送り出される心そのものになる。
次の瞬間、左右が再び立ち現れるとしても、問われるのは、どちらの技が正しいかだけではない。左右が二つに割れるより先に、関係へ向かって走り出せる心が、ここにあるかどうかである。次の一歩を決めるのは、左か右か――それとも、すでに「直ぐに馳せ行け」と発動した、人の心だろうか。

Commentary
Dōka 15 on this page presents the original: Sayū o ba / kiru mo harau mo / uchisutete / hito no kokoro wa / sugu ni haseyuke (左右をば／切るも払うも／打ち捨てて／人の心は／直ぐに馳せ行け). It clearly positions hito no kokoro (人の心), “the human heart-mind,” as “an integrated heart-mind that is neither emotion alone nor intellect alone” (kanjō demo chisei demo tandoku de wa nai tōgō sareta hāto-maindo; 感情でも知性でも単独ではない統合されたハート＝マインド). A critical vernacular rendering would be: “Cast aside the hand-level exchange of cutting and sweeping to the left and right; send the human heart-mind running in one straight line, immediately” (sayū ni kiru, harau to itta tesaki no ōshū wa sutete, ‘hito no kokoro’ o itchokusen ni, tadachi ni hashiraseyo; 左右に斬る・払うといった手先の応酬は捨てて、「人の心」を一直線に、ただちに走らせよ).
At the lexical core, uchisuteru (打ち捨てる) means “to cast something decisively away; to give it no further thought” (omoikitte suteru, kaeriminai; 思い切って捨てる・顧みない); sugu or sugu ni (直ぐ／直ぐに) means both “without bending—in a straight line” and “immediately” (magarazu, itchokusen; tadachi ni; 曲がらず〔一直線〕・ただちに); and haseru (馳せる) means “to run swiftly” or “to cause one’s thoughts to reach toward something” (hayaku hashiru; omoi o itaraseru; 速く走る／思いを至らせる). From these meanings arises a command: see through and relinquish the available maneuvers—the leftward and rightward cuts and sweeps—and send the heart-mind, the integrated psychophysical whole, straight forth without hesitation.
When this reading is gathered anew through the threads of Ueshiba Morihei’s Six Primers, its architecture becomes visible. The First Primer’s Bu = Uchū Genri (武＝宇宙原理), “Bu as cosmic principle,” provides the spine. The Second Primer’s Kami ya Hito to no Aiki (神や人との合気), “Aiki with Kami / Another / Others,” is brought down into the actual operation of the heart-mind, while the Third Primer’s Shinkon Ichinyo (心魂一如), “Heart-mind and Spirit, Inseparable,” establishes an unwavering center. The Fourth Primer’s Wagō Bika (和合美化), “Harmonious Unification and Beautification,” gives the telos—the answer to the question of where the heart-mind is to be sent. The Fifth Primer’s 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,” carries this discipline down into the smallest units of daily life. The Sixth Primer’s ‘Shiai’ no Minamoto ni Shitagau (「至愛」の源に順う), “Follow the Source of ‘Supreme Love,’” becomes the highest ground upon which the others depend. As their final reckoning, Dōka 15 gathers the vector of practice into a single line: do not permit the heart-mind to lose itself among left and right—the branching alternatives of technique—but send the heart-mind straight forward, at once.
Adding the momentum of the preceding three poems makes the sequence still clearer. Dōka 12’s ame-tsuchi no iki ni makasetsutsu (天地の息にまかせつつ), “entrusting oneself to the breath of heaven and earth,” gives rhythm to sugu ni (直ぐに), “at once.” Dōka 13’s seigan (清眼), “clear eye,” refines the discernment required to perceive a straight line, while Dōka 14’s mae zo mietari (前ぞ見えたり), “what lies ahead has come into view,” establishes the disposition of sending the heart-mind into the matter directly before it. Dōka 15 therefore presupposes the alignment of breath in Dōka 12, eye in Dōka 13, and the immediately present in Dōka 14. Upon that foundation, it sets aside the left-and-right maneuvers of cutting and parrying and sends “the heart-mind itself” ahead. In one brief sequence, it drives home an aiki discipline in which relationship and will—the heart-mind—pass through before technique.
A one-sentence vernacular summary
“Cast aside the cuts and sweeps to the left and right, and let the human heart-mind run straight ahead.”
Supplement on waka rhetoric: From sayū (左右) to sugu (直ぐ)
The rhetorical core that must still be named in this poem lies not in a simple two-part construction in which the kami-no-ku (上の句), the upper verse, merely lists techniques and the shimo-no-ku (下の句), the lower verse, then preaches about the heart-mind. Its deeper structure gathers two terms into one, horizontal branching into a single forward axis, and the transitive manipulation of external things into the activation of the heart-mind itself. The moraic count—sa-yu-u-o-ba / ki-ru-mo-ha-ra-u-mo / u-chi-su-te-te / hi-to-no-ko-ko-ro-wa / su-gu-ni-ha-se-yu-ke (さ・ゆ・う・を・ば／き・る・も・は・ら・う・も／う・ち・す・て・て／ひ・と・の・こ・こ・ろ・は／す・ぐ・に・は・せ・ゆ・け)—falls without excess or deficiency into the classical 5–7–5–7–7 form. The seventeen morae of the upper verse are crowded with the branching terms sayū (左右), “left and right,” kiru (切る), “to cut,” and harau (払ふ), “to sweep or parry.” The fourteen morae of the lower verse, by contrast, narrow into the single subject hito no kokoro (人の心), “the human heart-mind,” and the single trajectory haseyuke (馳せ行け), “race forth.” The form itself becomes a vessel that compresses multiple alternatives into one line of motion.
The opening word sayū (左右), “left and right,” is at once an antithetical compound that folds two opposed terms into one word and a merism that names both extremes in order to encompass the entire field between them. The second line, kiru mo harau mo (切るも払ふも), “whether cutting or sweeping,” then repeats the focus particle mo (も). This repetition embraces not merely a binary choice between cutting and sweeping, but the whole class of technical selections to which they belong. Although “left,” “right,” “cutting,” and “sweeping” each indicate particular directions and methods, they simultaneously become a synecdoche for the technical system as a whole.
The contrastive o ba (をば) in sayū o ba (左右をば) also corresponds to the topical wa (は) in hito no kokoro wa (人の心は). The former focuses attention upon the object to be discarded; the latter focuses attention upon the subject that is to begin running. No particle such as zo, namu, ya, ka, or koso (ぞ・なむ・や・か・こそ), together with its specially governed concluding form, appears to establish kakarimusubi (係り結び) in the narrow grammatical sense. It is therefore more precise to read the construction as a correspondence of focus and parallelism produced by o ba / mo … mo / wa (をば／も……も／は), rather than as kakarimusubi proper.
The third line, uchisutete (打ち捨てて), contains a still subtler auditory fold. Because the martial verbs kiru (切る), “cut,” and harau (払ふ), “sweep or parry,” have already appeared, the ear momentarily receives uchi (打ち) as a third technique: cut, sweep, strike. Only after hearing sutete (捨てて), “casting away,” does the listener resegment the phrase. Uchi is not an independent verb of striking, but a prefix-like and intensifying component of the compound verb uchisutsu (打ち捨つ), “to cast utterly away.” The very sound that seems poised to continue the catalogue of techniques reverses into a word that discards the entire catalogue.
This is not an orthodox kakekotoba (掛詞) based upon two fully distinct homophones, but it is a kakekotoba-like auditory weave: the preceding context temporarily destabilizes the boundary by which the word is heard. The repetition te-te (て・て) within sutete (捨てて) also remains grammatically open to what follows while sounding, at the level of rhythm, like a pair of quick incisions. Before the poem explains that technique must be discarded, it transforms the uchi heard as a technique into part of the word for discarding—within the listener’s own ear.
From this perspective, the previously noted sanku-gire (三句切れ), or third-line cut, is more accurately called a “semantic fold placed in the third line” or a “third-line-cut-like modulation” than a strict break at which the sentence closes completely. The conjunctive particle te (て) in uchisutete (打ち捨てて) connects adverbially to the principal command in the lower verse, haseyuke (馳せ行け), “race forth.” A full stop cannot therefore be placed after the third line without breaking the grammar. The syntax continues without severance, while the semantic center and the locus of agency turn dramatically from external techniques toward the inner heart-mind. Because a true phrase break is generally recognized through syntactic or semantic closure, the decisive feature here is not severance but a fold arising in the midst of continuity.
Nor is this ku-matagari (句跨がり) in the narrow sense, where a word itself crosses the boundary between a five- and seven-mora line. Each phrase remains within its line, but its syntactic dependency is sent onward into the next. Sayū o ba (左右をば) waits for the verbs in the following line; hito no kokoro wa (人の心は) waits for the predicate in the final line. That condition of waiting prevents the poem from coming to rest before its final yuke (行け), “go.”
Several overlapping engo-like associative clusters also operate within the vocabulary. The first is a field of martial technique and direction: sayū–kiru–harau–uchi (左右―切る―払ふ―打ち), “left and right—cut—sweep—strike.” The second is a field of purification and rectification: harau–sutsu–kokoro–sugu (祓ふ―捨つ―心―直ぐ), “purify—cast away—heart-mind—straight.” The third is a field of journeying and motion: sugu–hasu–yuku (直ぐ―馳す―行く), “straight—race—go.”
In classical waka, however, engo (縁語) is not established merely by gathering words that happen to be semantically similar. Clear boundaries are difficult to draw regarding how much customary or traditional association must be present. In this poem, it is therefore more judicious to speak of “engo-like semantic fields” or “associative word clusters” than to declare them engo in the strictest sense. Waka rhetoric commonly allows a kakekotoba to sustain two contexts through the engo surrounding it. Seen in that light, harau / harau (払ふ／祓ふ), “sweep away / purify,” is not an isolated play of sound. Its religious meaning is raised by the surrounding vocabulary of casting away, rectifying the heart-mind, and proceeding straight ahead.
Sugu (直ぐ), “straight” and “immediately,” likewise sets two meanings to work simultaneously within a single activation. This is not a conventional kakekotoba that layers two differently written words upon one sound, but a semantic superimposition that commands both spatial directness and temporal immediacy. The opening sayū (左右), “left and right,” spreads out two horizontal poles; sugu (直ぐ), immediately before the final movement, erases that horizontal axis and reconstructs it as one straight line. Although the word mae (前), “forward,” never appears explicitly, the command yuke (行け), “go,” follows only after left and right have been discarded. The direction that remains therefore rises of itself as forward. Through this directional antithesis, the planar alternatives of left and right are transformed into the axial line of sugu.
Personification and mitate (見立て), poetic figuration or “seeing-as,” become still more pronounced in hito no kokoro wa / sugu ni haseyuke (人の心は／直ぐに馳せ行け), “as for the human heart-mind, race straight forth.” In the ordinary expression kokoro o haseru (心を馳せる), “to send one’s heart or thoughts toward something,” a person causes the heart-mind to reach into the distance. Here, however, kokoro (心), “heart-mind,” is made the topic and agent through wa (は): the heart-mind itself races and goes. That which is conventionally sent becomes the one that runs.
Haseyuke (馳せ行け) is a compound expression of motion that joins hasu (馳す), “to race,” expressing velocity and manner of movement, with yuku (行く), “to go,” expressing direction and progression. It figures the heart-mind as a runner and, still further, as an unspoken koma (駒), a steed. The upper verse presents a transitive sequence—kiru, harau, uchisutsu (切る・払ふ・打ち捨つ), “cut, sweep, cast away”—in which action is directed upon an object. The closing line turns instead toward an autonomous movement in which the heart-mind itself runs onward. The poem’s transition is therefore not merely one “from technique to spirit.” It restructures agency: the subject that attempts to divide, sweep aside, and process the external world withdraws, and motion and direction are returned to the heart-mind itself.
The final line employs neither taigendome (体言止め), a nominal ending, nor an exclamatory ending. It concludes with the imperative yuke (行け), “go.” No explicit marker of a cut, such as ya, kana, or keri (や・かな・けり), is used. Instead, the poem makes the final inflected form itself the blade-point of the utterance. It does not become still as an object of contemplation; it passes directly into action. The imperative strongly closes the grammar of the poem, yet the motion expressed by yuku (行く), “to go,” continues beyond the poem. Its yoin (余韻), lingering resonance, remains not as a quiet echo but as a movement still receding into the distance.
It is likewise difficult to identify a conventional makurakotoba (枕詞), utamakura (歌枕), or honkadori (本歌取り). Nor is the upper verse a formal joshi (序詞), a prefatory phrase that introduces a particular word through sound or metaphor. It is better understood as a joshi-like prelude that establishes the condition upon which the lower verse’s command becomes possible. Even under approaches that identify a joshi through contextual transition and connection to the poem’s central purport, these three lines are not an ornament that can be detached from the main meaning. They are incorporated into the command itself as the very act of discarding.
Dōka 15 thus ceases to be a poem that merely explains from outside the maxim, “Do not be distracted by left and right; go straight ahead.” It raises the two poles of left and right, multiplies the branching through mo … mo (も……も), reverses uchi (打ち) from martial technique into relinquishment, passes the chain of transitive verbs into the heart-mind’s own running, and, through its final imperative, sends the reader’s speaking mouth and body beyond the poem. Language does not merely describe the heart-mind’s direct advance. The grammar and sound of the poem themselves fold the heart-mind that would scatter toward left and right into a single line and set it in motion: sugu ni haseyuke (直ぐに馳せ行け)—“race straight forth, at once.”
Speech Act Theory
Reconsidered through Austin’s (1962) framework, the locutionary act of Dōka 15 lies first in its articulated content: it presents the technical vocabulary of sayū, kiru, and harau (左右・切る・払ふ), “left and right, cutting, and sweeping,” momentarily checks that sequence at the third-line-cut-like fold, transfers the topic to hito no kokoro (人の心), “the human heart-mind,” and pours it into the imperative sugu ni haseyuke (直ぐに馳せ行け), “race straight forth, at once.”
Between the first two lines, sayū o ba / kiru mo harau mo (左右をば／切るも払ふも), and the fourth, hito no kokoro wa (人の心は), there is a correspondence of focus formed by o ba / wa (をば／は). Between the third line, uchisutete (打ち捨てて), “casting away,” and the fifth, haseyuke (馳せ行け), “race forth,” there is a correspondence of motion: release answers propulsion. Through this fold, the verbal center of gravity shifts from “what is to be handled” to “where it is to be sent,” from the enumeration of techniques to the vector of the heart-mind. If the kakekotoba of harau / harau (払ふ／祓ふ), “sweep away / purify,” is allowed to stand, what is discarded is not merely a set of manual options, but the clouding that arises as reactive response itself.
The core of the illocutionary act is therefore not explanation but injunction—and not merely an injunction to move quickly. Because sugu (直ぐ) layers “immediately” upon “straight,” its illocutionary force bears both temporal immediacy and ethical straightness of heart. The perlocutionary act consequently appears within the awareness of the reader or practitioner: it pares away the hesitation that clings to the branching alternatives of left and right, cutting and sweeping; gathers the heart-mind into a single point; and sends that point forward.
Before it is a poem that teaches technique, then, this poem functions as one that cuts off the motion of hesitation and starts the motion of the heart-mind. To borrow Austin’s terms, it commands in the act of saying and, by saying, seeks to bring a straight and immediate activation into being.
Coda
To “cast left and right away” is not to erase left and right, cutting and sweeping, from practice. What is relinquished is the order that allows those branches to stand before the “human heart-mind” and entrusts the root of action to the calculation of which technique should be chosen. When the heart-mind halts between left and right, technical possibilities may multiply even as the relationship with the other grows thin. When the heart-mind is sent first, by contrast, technique is no longer sovereign. It is born anew as the momentary form required to let that relationship pass through.
For this reason, sugu (直ぐ), “straight and at once,” is neither a rigid line nor a thoughtless charge. Read through the Six Primers, it is a living axis: grounded in Bu as cosmic principle, opened through Aiki with another, held in the inseparability of heart-mind and spirit, directed toward harmonious unification and beautification, trained within the everyday body as dōjō, and illuminated by the source of “Supreme Love.” Such a heart-mind may curve, answer, and turn without limit in outward form while remaining unbent at its root. To be “straight” is not to force the world into a single line, but to remain rooted in relationship amid a world that continually branches.
The conjunctive te (て) of uchi-sutete (打ち捨てて), “casting away,” likewise speaks relinquishment without closing the sentence; it carries the utterance directly onward into hase yuke (馳せ行け), “race forth.” The poem does not supply the correct answer to the choice between left and right. It restructures the grammar of a heart-mind sinking into recursive selection—from branching into continuation, from processing into activation. The instant the imperative is voiced, the reader is no longer merely contemplating a command. The reader becomes the very heart-mind that the command sends forth.
Left and right will undoubtedly arise again in the next moment. Yet the question is no longer only which technique is correct. It is whether, before left and right divide the field in two, there is a heart-mind already capable of racing into relationship. What, then, determines the next step—left or right, or the human heart-mind already set in motion by sugu ni hase yuke (直ぐに馳せ行け), “race straight forth, at once”?
