Rishi: Traditionally connected with Bṛhaspati/Āṅgirasa lineages (as in RV parallels); in VS transmission treated as śruti-mantra without separate r̥ṣi rubric in many paddhatis.
Devata: Brahmaṇaspati (Bṛhaspati).
Chandas: Triṣṭubh (RV-style cadence; to be verified against pada-count in the local recension).
O Lord of sacred speech, thou art the guide of this (rite): take heed of the well-spoken hymn, and quicken the offspring. All that is auspicious which the Gods do favour—may we speak what is great in the assembly of worship, rich in goodly heroes.
