Notes
1 Because Line 3‘s ことふる can plausibly be read as 言古る (to make [it] old by over‑telling) and as 事触る (to proclaim), reading it as a deliberate kakekotoba honors classical waka technique and elegantly explains the culminating contrast: the rock’s “voice” is pure precisely where no one proclaims it and where no one talks it into cliché.

山(さん / やま; san / yama)— mountain.
水(すい / みず; sui / mizu)— water.
山水(さんすい / やまみず; sansui / yamamizu)— mountains and waters / rivers; in Japanese poetic usage, often the natural landscape of mountain streams; nature and its beauties.
山水に(さんすいに / やまみずに; sansui ni / yama mizu ni)— “amid mountain waters / mountains‑and‑waters (landscape)”; evokes mountain streams and, more broadly, classical “mountain–water” landscape ideal central to East Asian aesthetics.
あたりて / 当りて(atari‑te)— (連用形 + 接続助詞) → “striking / impinging, and …”, “upon encountering / being in the presence of” (i.e., when in the presence of the mountain waters).
立たぬ(tata‑nu)— (未然 + 打消) → “(a rock that) does not move/stand up (i.e., stands fast, unbudging)”; grammatically, 立た + ぬ, the 未然形 of 立つ plus the negative auxiliary ぬ in its attributive form, so as bungo it means “not standing / not rising / not moving”, modifying a following noun; not the perfective ぬ of a form like 立ちぬ; register carries more than bare physical “standing”; in Kojiki-related diction it can also suggest emergence or grounded emplacement, so the negation here reads as steadfast groundedness rather than simple absence (see Space-Coyote, 2026).
岩(いわ; iwa)— rock, boulder; crag, cliff; anchor.
立たぬ岩(たたぬいわ; tatanu iwa)— (“the rock that does not [a]rise / move / stand”); more idomatically, “the voice of the rocks (i.e., the sound of rocks in the mountain stream) which does not stand (i.e., remains unmoving, still); suggests immovable, immovability, steadfast, and steadiness, resonant with 不動心 (fudōshin) in budō: an unwavering, centered mind; the grammar is the attributive −ぬ (classical negation) modifying 岩; the negative 立たぬ emphasizes that the sound is not theatrical, not forced, but natural and inherent.
声(こゑ; koe)— voice, sound; tone; intonation, punctuation; accent.
岩声 / 岩聲(いわこゑ; iwa koe)— “the rock’s voice” personifies natural sound, common in Shintō-inflected poetics where nonhuman things are animated with spirit and “voice.” Here it’s the sound of water meeting rock.
こそ(koso)— classical kireji in upper phrase, giving emphasis and cutting effect: “it is precisely that…”.
岩声こそ(いわこゑこそ; iwa‑koe koso)— (強意係助詞こそ) → “indeed the rock’s voice …”.
清(きよ; kiyo)— cleanly; purely.
清く(きよく; kiyoku)— (形容詞連用形) → “purely / clearly / with purity”.
岩声こそ清く(いわこゑこそきよく; iwa‑koe koso kiyoku)— personifies the sound of water striking stone; こそ gives emphatic focus: “indeed the rock’s voice (is) pure …”. The purity is adverbial 清く, modifying what follows.
ことふる / 言古る / 事降る(koto‑furu) — two classical homophones (言古る “to become worn by being oft‑spoken” vs. 事触る “to proclaim / spread a notice”). 言古る (ことふる) “(words) become ‘old’, hackneyed by being oft‑repeated,” i.e., to be talked into cliché; cf. 言古る/事古る in major dictionaries. 事触る (ことふる) “to proclaim, to spread (a notice / message)” — attested nominal 事触れ (ことぶれ) “proclamation, circulating announcement”; both senses fit “since there is no one to (koto‑furu)”: no one to proclaim and no one to talk it to death—hence purity; kakekotoba is a standard device in waka to layer meanings in minimal on; 事降る: literally “things descend / events fall”. In Buddhist or Shintō poetic usage, “事降る” could mean “the spiritual matter falls down / manifests”, or “the event happens”. Could also be read as “koto furu” = “sound falls (as a matter)”.
人も(hito mo)— “even a person / anyone”.
なければ(nakere‑ba)— (已然 + 接続助詞) → “since there is none / because there is no …”.
人もなければ / 人も無ければ(ことふるひともなければ; hito mo nakere-ba) — “neither is there a person (who)…”; i.e., no one to praise / appreciate it.
ことふる人もなければ(ことふるひともなければ; kotofuru hito mo nakere-ba)— uses older verb sense of kotofuru (“to speak”; “to announce”; “to celebrate”). With no human speech—no proclamation or praise—the sound remains 清く (kiyoku, “pure / clear”). This aligns with wabi–sabi sensibilities: unadorned nature unsullied by human ornament or ego.
Syntactic note (kakarimusubi). The emphatic particle こそ classically links to an 已然形 ending later in the sentence; here that function is satisfied by なけれ in なければ. This is normal bungo usage.
Bungo morphology. Negative attributive 立たぬ, connective あたりて, emphatic こそ with 已然形 resolution at なければ—all canonical features of classical grammar.
Historical kana. Forms such as 岩聲(いはごゑ) reflect pre‑1946 orthography and Heian‑based phonology used in literary diction.
31‑on target with tolerance. Presenting the text in five verses may yield a single ji‑amari (line 3), which remains within historically attested latitude for waka composition and reception.
Waka framing. The kami‑no‑ku / shimo‑no‑ku split captures the classical pivot between scene‑setting (nature image) and reflective turn (moral / spiritual statement), aligning with standard waka pedagogy.
Pivot‑word poetics. Reading ことふる as a kakekotoba is squarely within Heian‑style techniques to compress layered meanings into the on‑budget.
Nature as vehicle of ethos. Personifying 岩声 (“voice of the rock”) resonates with long‑standing waka practice of letting landscape carry ethical or affective insight.
Shintō / Ōmoto background. Ueshiba’s religio‑philosophical milieu drew on Shintō concepts and Ōmoto influences (via Deguchi Onisaburō). The poem’s image—water striking rock whose voice is pure—is legible against misogi (purification by water) and the idea that nature articulates divine order (kami presence) without human mediation.
Kotodama (word‑spirit): The ending clause ことふる人もなければ plays with the power (and danger) of human koto (words). In Shintō discourse, words are efficacious; purity often entails restraint of verbal interference—letting the world “speak” unforced. Scholarly treatments survey kotodama as belief and rhetoric in Japanese religion and culture.
Aikidō dōka as ethical instruction. Dōka (poems of the way) in Ueshiba’s corpus articulate budō ethics in a classical register; this specific poem is transmitted in modern aikidō collections and commentaries. Read thus, purity of the rock’s voice suggests authentic principle revealing itself when egoic proclamation ceases.
Yoin (余韻). The final line “人も無ければ” leaves a lingering emptiness, inviting the reader’s reflection, which is typical of classical Japanese poetic aesthetics (c.f. Kornicki, 2017).

解説
第42首は「山水に/あたりて立たぬ/岩声こそ/清くことふる/人もなければ」──批判的口語訳にすれば、「山の水がぶつかっても微動だにしない岩の“声”は、まさに澄んでいる。だって、それを言い立てて(ことふる)古びさせる人が誰もいないから」という趣旨です。ここでことふるは、ページの注が示すように「言古る(言い古す)/事触る(布告する)」の掛詞で、「誰も称揚も布告もしていないからこそ純度が保たれる」を導きます。またこそ…なければの係り結びが「清く」の焦点を高め、立たぬ岩の像は武道で言う不動心の比喩として読める、と本ページは丁寧に解説しています。
この読みは、植芝盛平の六つのプライマーの糸にそのまま通ります。プライマーの第一原理〈武=宇宙原理〉は「自然の理(岩声)が人為の喧噪(ことふる)を要せず自ずと明らかになる」座標を与え、プライマーの第二原理〈人との合気〉は「相手の力(山水)を受けても騒がず、中心(岩)にいて響かせる」実践を示します。プライマーの第三原理〈心魂一如〉は立たぬの無隙な統一、プライマーの第四原理〈和合美化〉は称揚よりも実質の清さを価値基準に、プライマーの第五原理〈体=道場、心=修業者/修行者心/学び手〉は日々の稽古で“音を立てずに響く”身づくりを促し、プライマーの第六原理〈「至愛」の源に順う〉はことば以前の清明さを拠りどころに据えます。つまりこの一首は、「語る前に、澄んで在る」という運用原理を六つの導入章で運転可能にした形です。
直前の三首とも噛み合います。第39首が説く「言向け勧め/愛の剣」は言葉の力を最後に用いる倫理であり、第41首は「物見で“や”と自拍を立て、他人の拍に移るな」と内なる拍を護る戒め、第40首は「月の出没を“本当に知る者”はいない」という謙虚さを据えました。第42首はその底面で、過剰な宣言や自慢(ことふる)を退け、静かな不動の中心から“清い声”を立ち上げよと締めくくります。稽古での翻訳はシンプルです──まず澄む(プライマーの第六原理)/ぶれない(プライマーの第三原理)/合わせて導く(プライマーの第二原理・プライマーの第四原理)/日々で体化(プライマーの第五原理)、そして必要以上に語らない(第39~41首)。そのとき、技も場も「清く」響く、とこのページは教えています。
口語要約のひとこと
「山の水が当たっても動かない岩の声こそ澄んでいる――だって、それをわざわざ言い立てる人なんていないからだ。」
詩法上の補遺――流れる構文、立たぬ岩、消える人
さらにこの一首で鋭いのは、五句がほとんど一度も文法的に閉じない、連鎖的な句跨りである。「山水に」は格助詞によって次句を待ち、「立たぬ」は連体形として「岩声」へ渡り、「岩声こそ」は結びを遠く呼び寄せ、「ことふる」はさらに「人」を修飾し、結句さえ「なければ」という理由・条件の接続形で開いたまま終わる。音数上は五句に分かれながら、構文は山水のように句境を越えて流れつづけ、その流れのただ中に、既注の字余りを帯びた第三句「岩声こそ」が岩のような抵抗点をつくる。したがって第三句は、三句切れの聴感を持ちながらも文法的にはなお下句へ係り続ける「折り目」であり、詩形そのものが〈流れる水/立たぬ岩〉を演じている。
とりわけ第四句頭の「清く」は、聴覚上の統語的な両掛かりとして働く。耳はまず「岩声こそ清く」と受け、岩声の清澄をいったん成立させるが、その直後に「清くことふる」とも再分析させられる。この後ろ向きと前向きの二重の係りが、語彙上の掛詞「言古る/事触る」を一語の内部だけに留めず、構文全体へ押し広げるのである。しかも「ことふる」の対象は明示されないため、岩声を宣べ伝えること、人の言葉が言い古されること、出来事や言葉が触れ回られることが、目的語の省略された空所へ重なって入る。
第二・三句の「立たぬ岩声」と第四・五句の「ことふる人」は、対句的に照応しながら、意味の向きを交差させている。動かぬものには声があり、声を立てるはずの人には存在がない。さらに第二句の否定「ぬ」と結句の否定「なければ」が、中央の「岩声こそ/清く」を両側から囲み、二重の否定の内側にだけ声と清さを残す。「こそ」が岩声を卓立させる一方、「も…なし」は人を一人さえ残さない添加的・全面的な否定となるため、係助詞の対照だけでも発話の権威が人から岩へ移される。古典語研究でも「こそ」は焦点化・卓立に関わり、「も」は添加的な取り立てに位置づけられるため、この二助詞の配置は単なる文法上の呼応以上の構図を形づくる。
音の運びにも、意味から離れない反復がある。「あたりて立たぬ」ではタ行音が「あたりて・たたぬ」と畳みかけ、山水が岩へ当たる打撃を短く刻む。その直後、「岩声こそ/清くことふる」ではカ・ガ行と「こ」の音が「声―こそ―清く―こと」を鎖のようにつなぎ、衝突の音を発話の音へ変えてゆく。これは「山水―あたり―岩―声―清く」という自然・音響の縁語場と、「声―言―こと―触る―人」という発話・伝達の縁語場とが重なる箇所でもある。掛詞「ことふる」はその二つの語彙場を結ぶ蝶番となり、水の物理的な衝突を、言葉の社会的な流布へ折り返す。
また「岩声」は、単なる擬人化だけでなく換喩としても働く。本来その音は、水と岩との接触のあいだに生じるにもかかわらず、一首はそれを水の声ではなく「岩声」と呼び、出来事の結果を受けた岩の所有する声へ移す。打つ側ではなく、打たれてなお動かぬ側が語るという主客転換である。そのため「立たぬ」は、単なる静止の描写ではなく、否定によって不動を強める逆説的な表現となる。動かぬものが響き、語る者のいないところで言葉が起こる――この二重の逆説が、自然を人間の比喩として利用するだけでなく、人間の発話を自然の響きの一変奏へ引き下ろしている。
「清く」にも同様の重層がある。声の澄明という聴覚的性質、清水の透明さ、禊・祓に通じる祭祀的清浄、言葉を言い古さない倫理的純度が、一つの連用形へ集められている。したがって「清く」は、音を清浄という倫理・祭祀の尺度で捉える通感的修飾であると同時に、山水と岩声とことばを結ぶ縁語的な媒介でもある。ここでは「清い声」が先に存在するのではない。山水が当たり、岩が立たず、人が退くという関係そのものから、清さが発生している。
結句「人もなければ」は、先に置かれた「岩声こそ清く」の理由を後から差し出す倒置法であると同時に、接続助詞で止める言いさし様の終止でもある。「なければ」の先には文法上なお何かが続き得るのに、そこにはもう続きをことふる人がいない。この句末開放こそが、既注の余韻を形式面から生み出す仕掛けである。体言止めのように像を一つの名へ凝固させるのではなく、理由だけを残して結論から退き、響きの行方を岩と山水へ返す。人の不在は内容として述べられるだけでなく、完結する発話主体を文末から消すことによって、構文上でも実行されている。
さらに典故の層として、「山水」「岩声」「清く」「人へ伝えることの不在」という連鎖は、蘇軾の偈を引く道元『正法眼蔵』「渓声山色」を強く想起させる。そこでは渓流の声が仏の広長舌、山の姿が清浄身とされ、夜来の八万四千偈を後日いかに人へ伝えるかが問われる。曹洞宗の公式英訳・解説も、この巻の主題を、自然界が仏身と仏法の表現となること、すなわち無情が法を説くこととして説明している。また国立国会図書館のレファレンス資料は、この七言絶句を蘇軾「贈東林総長老」と同定している。
直接の借用を証明する資料がない以上、これを本歌取りと断定することはできない。しかし、本説取りに近い典故的反照として読むなら、植芝の一首は蘇軾の結び「いかに人へ示そうか」を、「ことふる人もなければ」へ反転したことになる。渓声を人へ伝える困難ではなく、人が伝えようとしないからこそ岩声は清い、と置き直したのである。そのとき「岩声」は自然を飾る比喩ではなく、宣者なき説法そのものとなる。何者も所有せず、誰も言い立てず、それでも絶えず響いている――その声だけが、言い古されることなく山水の中に残る。
発話行為理論
オースティン(Austin, 1962)の発話行為論(Speech Act Theory)に寄せて見るなら、第42首の発話行為(locutionary)な相は、「山水が当たっても立たぬ岩の声は清い。なぜなら、それをことふる人がいないからだ」という命題内容にある。ただし、この一首では、その命題内容そのものがすでに言語論的に折り返されている。第一・二句の「あたりて立たぬ」は第四句の「清くことふる」へ折り返され、物理的な〈当たり〉が言語的な〈ことふる〉へと転位する。さらに第三句「岩声こそ」は第五句「人もなければ」へ折り返され、声は立ちながら人の声の主体は退いている。したがって、ここで語られているのは単なる叙景ではなく、「誰が、どのように、ほんとうに語るのか」という問いを内蔵した発話行為である。掛詞「ことふる」が「事触る」と「言古る」を同時に立てるため、発語内容もまた二重化される。
そのうえで発語内行為(illocutionary)は、自然の純声を称揚しつつ、人為の布告や言い立てを戒める教戒として働く。ここでの要点は、沈黙そのものの礼賛ではない。誇示的な言語、言い古して力を失った言語、そうした〈ことふる〉を退けることで、ほんとうの声の在り処を示しているのである。ゆえに、この一首は「語るな」と命令しているのではなく、「道は言い立てられるほど濁る」という規範を、語ることによって行っている。しかも「こそ」の切れが焦点を岩声に集めるため、発話の権威は人ではなく、打たれても動かぬものの側へ移る。この逆説的な言い方そのものが、この一首の発語内行為の強さである。
最後に発語媒介行為(perlocutionary)は、読み手のうちに静けさ、羞恥、澄明を起こし、過剰に説明したり宣布したりする衝動を鎮めるところにある。第一・二句で水勢を聞かせ、第三句で「岩声こそ」と切り立て、第四句で掛詞により人の言語を差し挟み、第五句でその人影を消す。この運びが余韻を生み、「語らぬこと」よりもむしろ「語らずとも響くこと」へ感覚を導く。稽古の位相でいえば、技を言説で飾る方向ではなく、中心の不動から自然に響かせる方向へ身心を向けさせる効果であり、その静かな移行こそが、この一首の発語媒介行為な働きである。
コーダ
山水は岩を説得しない。岩もまた、山水に向かって己の不動を布告しない。流れるものと立たぬものとのあいだに、ただ声が生じ、その声は誰の所有にもならぬまま清くある。「人もなければ」が空けるのは、人間そのものの席ではなく、世界の響きへ自分の名を重ね、意味を先取りし、道を所有物として言い立てる者の席である。そこに残るのは無音ではない。宣者を要しない説法、説明より先に身体へ届き、称揚される前からすでに働いている声である。
この意味で「立たぬ」は、外から来る力を拒む硬直ではない。山水を受け、衝突を響きへ変えながら、なお中心を自己顕示へ明け渡さない不動である。稽古における清さも、触れられないこと、打たれないこと、揺さぶられないことから生じるのではない。触れられ、打たれ、揺さぶられる関係のただ中で、余分な自己主張だけが退くとき、技は誰かの標語ではなく、その場そのものの声となる。清さとは、何も起こらないことではなく、起こったものを濁らせる者が残らないことなのである。
そして解説もまた、この歌の尺度から免れない。掛詞をほどき、係り結びを追い、折り目と余韻を言葉にしても、最後の一語によって岩声がさらに清くなるわけではない。むしろ、解説が果たしうる最後の忠実さは、自らの結論をことふらず、響きの行方を山水へ返すことにある。これほど言葉を重ねたのち、なお残る修行とは、岩声の前から静かに退くことではないだろうか。
English Translation
Commentary
Poem 42 reads, sansui ni / atarite tatanu / iwagoe koso / kiyoku kotofuru / hito mo nakereba (山水に/あたりて立たぬ/岩声こそ/清くことふる/人もなければ)—or, in a critically sharpened colloquial rendering: “The ‘voice’ of a rock that does not so much as stir even when mountain water strikes it is truly clear. After all, no one is there to proclaim it—and, through such proclamation, wear it old.” Here, kotofuru (ことふる), as the page’s note indicates, is a kakekotoba (掛詞), pivoting between koto-furu (言古る, “to repeat words until they grow old”) and koto-furu (事触る, “to announce or proclaim”). It thus leads toward the thought that purity is preserved precisely because no one praises or proclaims it. The kakari-musubi (係り結び) of koso … nakereba (こそ…なければ) heightens the focus upon kiyoku (清く), “clearly” or “purely,” while the image of the rock that does not stir may be read as a metaphor for the fudōshin (不動心), or immovable mind, spoken of in budō. This page carefully unfolds both dimensions.
This reading threads directly through Morihei Ueshiba’s Six Primers. The First Principle, Bu = Uchū Genri (武=宇宙原理), “Bu = Cosmic Principle,” provides the coordinates upon which the order of nature—the rock-voice—reveals itself without requiring the clamor of human proclamation. The Second Principle, Hito to no Aiki (人との合気), “Aiki with Another,” shows the practice of receiving another’s force—the mountain water—without commotion, remaining at the center—the rock—and allowing the encounter itself to resonate. The Third Principle, Shinkon Ichinyo (心魂一如), “Heart-Mind and Spirit, Inseparable,” appears in the seamless unity condensed into tatanu (立たぬ), “does not stir.” The Fourth Principle, Wagō Bika (和合美化), “Harmonization and Beautification,” takes substantive clarity, rather than praise or acclaim, as its standard of value. The Fifth Principle, Tai = Dōjō, Kokoro = Shūgyōsha / Shugyōsha-Gokoro / Manabite (体=道場、心=修業者/修行者心/学び手), “Body as Dōjō; Heart-Mind as Practitioner / Ascetic / Learner,” encourages, through daily keiko (稽古), the formation of a body capable of “resounding without making a sound”—oto o tatezu ni hibiku (音を立てずに響く). The Sixth Principle, “Shiai” no Minamoto ni Shitagau (「至愛」の源に順う), “Follow the Source of ‘Supreme Love,’” places its trust in a lucidity prior to words. In other words, this poem renders the operating principle “Before speaking, be clear in one’s being”—kataru mae ni, sunde aru (語る前に、澄んで在る)—practicable through the six introductory chapters.
It also meshes with the three poems immediately preceding it. Poem 39’s “word-turning exhortation / sword of love”—kotomuke susume / ai no tsurugi (言向け勧め/愛の剣)—sets out an ethics that reserves the power of words for the final measure. Poem 41 guards the inward beat with the admonition to establish one’s own pulse with ya (や) at monomi (物見), and not to shift into another person’s beat. Poem 40 establishes the humility that no one “truly knows”—hontō ni shiru mono (本当に知る者)—the moon’s rising and disappearance. At their foundation, Poem 42 rejects excessive declaration and self-praise—another register of kotofuru—and concludes by calling forth a “clear voice” from a quiet, immovable center. Its translation into practice is simple: first become clear, in accordance with the Sixth Principle; do not waver, in accordance with the Third; join and guide, in accordance with the Second and Fourth; embody it from day to day, in accordance with the Fifth; and do not speak beyond what is necessary, in accordance with Poems 39–41. Then both technique and the place itself resound kiyoku (清く), “clearly” and “purely.” That is what this page teaches.
A one-line colloquial summary
“The voice of a rock that does not move even when mountain water strikes it is the very voice that rings clear—for no one goes out of the way to proclaim it.”
A supplement on poetic technique: Flowing syntax, the unmoving rock, the vanishing person
Still sharper in this poem is its chain of enjambments: across all five lines, the grammar almost never comes to a close. Sansui ni (山水に), “to the mountain water,” waits for the next line by force of its case particle. Tatanu (立たぬ), “does not stir,” crosses over in its attributive form into iwagoe (岩声), “rock-voice.” Iwagoe koso (岩声こそ) summons its resolution from far ahead. Kotofuru (ことふる) reaches still farther, modifying hito (人), “person.” Even the final line remains open, ending upon nakereba (なければ), a causal or conditional connective form. Although its meter divides the poem into five lines, its syntax continues to flow across their boundaries like mountain water. In the midst of that current, the already-noted extra mora of the third line, iwagoe koso (岩声こそ), creates a point of resistance like a rock. The third line therefore carries the aural impression of a third-line caesura, or sanku-gire (三句切れ), while grammatically continuing to bind the lower verse. It is a “fold”—orime (折り目)—at which one movement turns into another. The poetic form itself performs “flowing water / the rock that does not stir”—nagareru mizu / tatanu iwa (流れる水/立たぬ岩).
Most strikingly, kiyoku (清く) at the beginning of the fourth line operates, to the ear, as a syntactic double attachment. The ear first receives iwagoe koso kiyoku (岩声こそ清く), “the rock-voice indeed is clear,” and provisionally establishes the clarity of the rock-voice. Immediately afterward, however, the phrase must be reparsed as kiyoku kotofuru (清くことふる). This double pull, backward and forward, expands the lexical kakekotoba of koto-furu (言古る/事触る) beyond the interior of a single word and across the syntax as a whole. Moreover, because the object of kotofuru is never stated, several possibilities enter the same omitted space: proclaiming the rock-voice, human words becoming worn through repetition, and events or words being circulated abroad.
The second and third lines’ tatanu iwagoe (立たぬ岩声), “the rock-voice that does not stir,” and the fourth and fifth lines’ kotofuru hito (ことふる人), “the person who proclaims or wears words old,” answer one another antithetically even as their semantic directions cross. That which does not move possesses a voice; the person expected to raise a voice is nowhere present. Further, the negative nu (ぬ) in the second line and nakereba (なければ) in the final line enclose the central iwagoe koso / kiyoku (岩声こそ/清く) from either side, leaving voice and purity only within a double negation. While koso (こそ) makes the rock-voice stand forth, mo … nashi (も…なし) becomes an additive and exhaustive negation that leaves not even a single person behind. At the level of the focus particles alone, the authority of speech transfers from the human being to the rock. Studies of classical Japanese likewise associate koso with focus and prominence, while locating mo within additive focus. Their placement therefore forms a design exceeding mere grammatical concord.
The movement of sound also carries repetitions that never detach themselves from meaning. In atarite tatanu (あたりて立たぬ), the repeated t sounds of atarite and tatanu strike in succession, marking the mountain water’s impact upon the rock in short blows. Immediately afterward, in iwagoe koso / kiyoku kotofuru (岩声こそ/清くことふる), the k and g consonants and the recurring sound ko link koe—koso—kiyoku—koto (声―こそ―清く―こと) like a chain, gradually transforming the sound of collision into the sound of utterance. This is also where a natural-acoustic field of associated words—sansui—atari—iwa—koe—kiyoku (山水―あたり―岩―声―清く)—overlaps with a field of speech and transmission—koe—koto—koto—furu—hito (声―言―こと―触る―人). The kakekotoba kotofuru becomes the hinge joining those two lexical fields, folding the physical collision of water and rock back into the social circulation of words.
Nor is iwagoe (岩声) merely a personification. It also operates metonymically. The sound properly arises in the contact between water and rock, yet the poem calls it not the water’s voice but the “rock-voice,” transferring the result of the event to a voice possessed by the rock that receives the blow. This is a reversal of subject and object: not the striking side, but the side struck and nevertheless unmoved, is made to speak. Tatanu (立たぬ) thus becomes more than a description of stillness. Through negation, it becomes a paradoxical expression that intensifies immovability. That which does not move resounds; words arise where no speaker is present. This double paradox does more than employ nature as a metaphor for the human. It reduces human utterance to a single variation upon the greater resonance of nature.
Kiyoku (清く) carries a comparable stratification. The auditory clarity of a voice, the transparency of clear water, the ritual purity associated with misogi (禊) and harae (祓), and the ethical purity of language not yet worn old all gather within a single adverbial form. Kiyoku is therefore a synesthetic modifier that appraises sound according to an ethical and ritual measure, while also serving as an associative mediator among mountain water, rock-voice, and speech. Here, a “clear voice” does not exist beforehand. Clarity arises from the relation itself: the mountain water strikes, the rock does not stir, and the human being withdraws.
The final line, hito mo nakereba (人もなければ), is at once an inversion that supplies, only afterward, the reason for the preceding iwagoe koso kiyoku (岩声こそ清く), and a suspended, almost aposiopetic ending that stops upon a conjunctive particle. Grammatically, something may still follow nakereba; yet no person remains to kotofuru what would come next. This openness at the end of the line is precisely the formal mechanism that produces the already-noted yoin (余韻), the lingering resonance after the words have ceased. Rather than crystallizing an image into a noun, as taigendome (体言止め) would do, the poem leaves only the reason, withdraws from its own conclusion, and returns the course of the resonance to the rock and mountain water. Human absence is not merely stated as content. It is performed syntactically by removing from the sentence’s end the speaking subject who might have completed it.
At the level of literary allusion, moreover, the sequence “mountain water,” “rock-voice,” “purity,” and “the absence of transmission to another person” strongly recalls Keisei Sanshoku (渓声山色), “Valley Sounds, Mountain Colors,” in Dōgen’s Shōbōgenzō (正法眼蔵), which cites a gāthā by Su Shi. There, the voice of the mountain stream becomes the Buddha’s vast and eloquent tongue, while the form of the mountains becomes the pure body; the poem then asks how the eighty-four thousand gāthās heard through the night might later be conveyed to another person. The official Sōtō Zen English translation and commentary likewise describe the fascicle’s central theme as the natural world becoming an expression of the Buddha-body and the Buddha-Dharma—that is, the insentient preaching the Dharma. A reference resource of Japan’s National Diet Library further identifies the seven-character quatrain as Su Shi’s Zō Tōrin Sōchōrō (贈東林総長老), “Presented to Elder Zong of Donglin.”
In the absence of evidence proving direct borrowing, this cannot be identified conclusively as honkadori (本歌取り), the deliberate variation of an earlier poem. Yet, if read as an allusive counter-reflection resembling honzetsudori (本説取り), the drawing of a new work from an established source or story, Ueshiba’s poem reverses Su Shi’s closing question, “How might this be shown to another person?”—ikani hito e shimesō ka (いかに人へ示そうか)—into kotofuru hito mo nakereba (ことふる人もなければ), “because there is no person to proclaim it.” The problem is no longer the difficulty of conveying the stream’s voice to another person. Instead, the poem recasts the matter so that the rock-voice remains clear precisely because no human being attempts to transmit it. At that point, iwagoe ceases to be a decorative metaphor for nature. It becomes preaching without a proclaimer. Owned by no one, proclaimed by no one, and yet ceaselessly resounding—the voice alone remains within the mountain water, never worn old through repetition.
Speech-Act Theory
Read through Austin’s (1962) Speech Act Theory, the locutionary dimension of Poem 42—hatsuwa kōi (発話行為)—lies in its propositional content: “The voice of the rock that does not stir even when mountain water strikes it is clear, because there is no person to kotofuru it.” Yet in this poem, the proposition itself has already been folded back upon itself at the level of language. The first and second lines’ atarite tatanu (あたりて立たぬ) fold into the fourth line’s kiyoku kotofuru (清くことふる), as physical impact is displaced into linguistic proclamation. The third line’s iwagoe koso (岩声こそ) likewise folds into the fifth line’s hito mo nakereba (人もなければ): the voice stands forth while the human subject of that voice recedes. What is spoken here is therefore not merely a description of scenery, but a speech act containing within itself the question of who truly speaks, and how. Because the kakekotoba kotofuru simultaneously raises koto-furu (事触る), “to proclaim,” and koto-furu (言古る), “to wear words old,” the locutionary content is itself doubled.
The illocutionary act—hatsugo-nai kōi (発語内行為)—works as an admonition that praises the pure voice of nature while warning against human proclamation, ostentation, and self-advertisement. The point is not to praise silence in itself. By rejecting demonstrative language, language worn powerless through repetition, and the many forms of kotofuru, the poem indicates where the true voice resides. It therefore does not simply issue the command “Do not speak.” Rather, by speaking, it performs the norm that “the more loudly the way is proclaimed, the more clouded it becomes.” Moreover, because the break and focus of koso gather attention upon the rock-voice, the authority of utterance passes away from the human being and toward that which, though struck, does not move. This paradoxical manner of speaking is itself the strength of the poem’s illocutionary force.
Finally, the perlocutionary act—hatsugo-baikai kōi (発語媒介行為)—lies in awakening stillness, shame, and lucidity within the reader, thereby calming the impulse to explain too much or proclaim too loudly. The first and second lines make the force of the water audible. The third raises iwagoe koso (岩声こそ) like a sheer rock face. The fourth inserts human language by means of the kakekotoba. The fifth causes the human figure to disappear. This progression produces yoin, directing perception not toward mere “not speaking”—kataranu koto (語らぬこと)—but toward “resounding even without having to speak”—katarazu tomo hibiku koto (語らずとも響くこと). In the register of keiko, its effect is to turn the body-mind away from adorning technique with discourse and toward allowing technique to resonate naturally from the immovability of the center. That quiet turning is precisely the perlocutionary work of the poem.
Coda
Mountain water does not persuade the rock. Nor does the rock proclaim its own immovability to the water. Between that which flows and that which does not stir, a voice simply comes forth, remaining clear precisely because it never becomes anyone’s possession. The vacancy opened by hito mo nakereba (人もなければ), “because there is no person,” does not expel the human being. It empties the seat from which a person might lay a name over the world’s resonance, preempt its meaning, and proclaim the way as property. What remains is not muteness. It is preaching without a proclaimer—a voice that reaches the body before explanation and is already at work before praise.
In this sense, tatanu (立たぬ), “does not stir,” is not the rigidity that refuses an approaching force. It is the immovability that receives the mountain water, turns collision into resonance, and yet does not surrender its center to self-display. Clarity in keiko (稽古) likewise does not arise from never being touched, struck, or unsettled. It arises within the encounter itself, when what is unnecessary in self-assertion withdraws. Technique then ceases to be a slogan attached to a practitioner and becomes the voice of the place itself. Purity is not the absence of occurrence; it is the absence of anyone left to cloud what has occurred.
Commentary, too, must answer to this measure. It may unfold the kakekotoba, follow the kakari-musubi, and give names to the fold and its lingering yoin, yet no final sentence can make the rock-voice clearer than it already is. Commentary’s last fidelity is therefore not another proclamation, but a withdrawal that returns the resonance to the mountain water. After so many words, the final discipline is to step quietly aside and let the rock keep speaking.
