अंतरं तु तयोः कार्यं तथा हस्तचतुष्टयम् । मुंडकोपरि काष्ठं च दृढं कुर्याद्विचक्षणः
aṃtaraṃ tu tayoḥ kāryaṃ tathā hastacatuṣṭayam | muṃḍakopari kāṣṭhaṃ ca dṛḍhaṃ kuryādvicakṣaṇaḥ

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.
