太刀（たち; tachi） — sword; in classical poetry, the tachi often symbolized a warrior’s identity, strength, and honor.

せん太刀（せんたち; sen‑dachi） — 先太刀; sen (先) is the principle of initiative central to Japanese martial thought: go no sen (responding after), sen no sen (seizing the initiative as the attack forms), and sen‑sen no sen (pre-empting at a subtler, earlier moment). 先太刀 can mean “the one who moves first” (the attacking role) or “the initiating / first cut.” Ueshiba’s phrase tells the practitioner to assume the role of initiative decisively. 先(せん)太刀 is read sen-dachi here to foreground sen (“initiative”) as in sen‑no‑sen / go-no-sen, a core sword‑timing concept; 太刀 takes rendaku to ‑dachi in compounds. (For sen in budō timing, see “mitsu no sen”.)

天（てん / あめ; ten / ame）— heaven (space).

天に構へて（てんにかまえて; ten ni kamaete）— “hold to heaven”; points to the jōdan no kamae (high guard), with the sword raised overhead—poetically aligned with ten (heaven). In Japanese cosmology and budō pedagogy, practitioners often orient body-mind through the ten–chi–jin (heaven–earth–human) triad. Adopting a “heaven” guard cues uplifted spirit, expansive intent, and readiness to issue force from above. Practically, this evokes jōdan (upper stance), but the diction “天” also resonates with Ueshiba’s cosmology (Ten‑Chi‑Hito).

早くつめ（はやくつめ; hayaku tsume）— “close quickly”; tsume / tsumeru means to close the maai (combative interval) and apply seme (forward pressure). Classical teachings stress collapsing distance before the opponent stabilizes, initiative expressed spatially. 詰め is the imperative / command flavor in context (“close in promptly”). (On closing distance as core to kendō / kenjutsu timing, see modern analyses of seme, ma‑ai.) 

打（うち; uchi) — hit, strike, slap; beat up; act of beating up; changes noun to verb.

打逃し / 打ち逃し （うちのがし; uchi-nogashi）— “miss a strike / let (the opponent) slip the blow,” from 逃す（のがす）.

なば（naba）—  classical conditional na + ba (未然形 na of ぬ + 接続助詞 ば) ≈ “if / should it happen that…”.

打逃しなば / 打ち逃しなば （うちのがしなば; uchi‑nogashi naba）— “if the strike is missed / evaded”; older conditional form (‑naba) meaning “should it happen that….” The subject is intentionally fluid: if your initial blow misses or he slips it, the result is the same—your follow‑up must be immediate.

横に切るべし (よこにきるべし; yoko ni kiru beshi) — “cut horizontally”; prescriptive べし (“one ought to / must”) signals a tactical injunction: transition at once to a yokogiri (cross‑cut). In kata logic, a vertical or descending opening from jōdan often elicits a rearward or off‑line evasion; the horizontal line then intercepts that lateral movement.

べし（べし; beshi）—  classical modal marking obligation / appropriateness (“should, ought to”).

Tactical lesson. Ueshiba compresses a full tactical lesson into a single aphorism: seize initiative, take the high guard (heaven‑aligned posture), close maai without hesitation, and if the first action doesn’t land, change the cutting line to a horizontal cross‑cut. The line illustrates how classical budō weaves technique with cosmological orientation—moving from Ten (heaven) into decisive action within the human realm to shape Earth (position / space).

Orthography & forms. The text’s 旧仮名 (e.g., 構へて) and classical auxiliaries match bungo usage alive into early Shōwa, when Ueshiba composed and taught. The connective なば (na+ba) and modal べし are classical; they give conditional/prescriptive nuances typical of prewar didactic verse.

Meter. Read as above, the line is 31 moras in a 5–7–5 / 7–7 pattern, exactly the waka/tanka template. This is consistent with how Ueshiba’s dōka are curated by students and dojo lineages—as compact tanka‑like aphorisms.

Lexis. Martial terms like 先太刀, 構え, 切る are classical kenjutsu vocabulary readily used in waka diction; the prescriptive べし suits instructional poetry (道歌). (For “先” as timing doctrine in sword arts see kendō / kenjutsu pedagogy.)

“Ten” (Heaven) as stance and cosmology. The phrase 天に構へて carries a double register. Technically it signals jōdan (sword raised “to heaven”); symbolically it aligns with Ueshiba’s Ten–Chi–Hito cosmology and ritualized practice (misogi, kotodama). Religious‑studies work shows Ueshiba’s aikidō emerged at the intersection of martial training and new‑religion currents (notably Ōmoto), reading technique as ritual to harmonize with cosmic order.

Aikidō as ritualized ethics of force. Recent scholarship frames Ueshiba’s budō as ritual practice oriented to world‑reconstruction and harmony—an interpretive lens that clarifies why tactical lines (“close quickly; if the blow is slipped, cut crosswise”) sit inside a larger soteriological idiom. 

Anthropology of modern sword arts. Studies of kendō’s modern formation trace how older kenjutsu rhetoric (timing/initiative, sen) was re‑articulated in the 20th century; Ueshiba’s dōka inherit that vocabulary while redirecting it to an ethics of alignment rather than domination.
