अंतरं तु तयोः कार्यं तथा हस्तचतुष्टयम् । मुंडकोपरि काष्ठं च दृढं कुर्याद्विचक्षणः
aṃtaraṃ tu tayoḥ kāryaṃ tathā hastacatuṣṭayam | muṃḍakopari kāṣṭhaṃ ca dṛḍhaṃ kuryādvicakṣaṇaḥ
両者の間隔は四肘(四手)と定めよ。賢明なる者は、ムンダカ(柱)の上に木の梁を堅固に据え付けるべし。
Lomaharṣaṇa (Sūta) (deduced)
Scene: Two upright posts stand four hasta apart; a strong horizontal beam is lashed or mortised atop them; the builder checks alignment; the balance mechanism is about to be hung; the scene conveys readiness and solemnity.
Truth-seeking rites are not casual; they require skill, stability, and correct arrangement to uphold dharma.
No tīrtha is mentioned in this procedural verse.
Keep four hastas between the posts and secure a strong beam atop them.
