अध्याय १६ — शङ्कर-उमा-वरदानम् तथा तण्डि-स्तुतिः (Śaṅkara–Umā Boon-Granting and Taṇḍi’s Hymn)
यजुर्भियत्र्तरिधा वेद्यं जुद्धत्यध्वर्यवो5ध्वरे । सामभिर्य॑ च गायन्ति सामगा: शुद्धबुद्धयः
yajurbhir yatra tridhā vedyam śuddhyaty adhvaryavo 'dhvare | sāmabhir ya ca gāyanti sāmagāḥ śuddha-buddhayaḥ ||
Vāyu dit : «Dans ce rite sacré, l’autel est purifié de trois manières par les formules Yajus, tandis que les prêtres Adhvaryu accomplissent le sacrifice. Et là, les chantres du Sāma, l’esprit purifié, entonnent les hymnes du Sāma.»
वायुदेव उवाच
The verse links outer ritual purity with inner purity: the sacrifice is properly established when the altar is ritually purified through Yajus-formulas and when Sāma-hymns are sung by chanters whose minds are themselves purified. Correct performance (karma) and purified intention/understanding (buddhi) together uphold dharma.
Vāyudeva describes the functioning of a Vedic sacrifice: Adhvaryu priests employ Yajurveda formulas to purify and prepare the altar in a threefold manner, while Sāmaveda chanters sing the Sāman melodies. The description emphasizes the coordinated roles of different Vedic specialists and the sanctity of the rite.
