• śaṅkha — conchshell
  Viṣṇu's pāñcajanya. The conch's sound is itself a form of nāma. Gauḍīyas read its appearance in any Vaiṣṇava-context as the Lord announcing His own presence through air.
• sūta-māgadhāḥ — sūta and māgadha bards
  Two professional reciter-classes. Gauḍīyas note that the recital culture preserved hari-kathā long before written-down texts; the sūta-māgadhas of this verse are the same class as Sūta Gosvāmī of Naimiṣāraṇya.
• gandharvyaḥ — female Gandharvas
  Celestial singers. Their participation marks the yajña as cosmically attended. Gauḍīyas note that Vaiṣṇava worship draws attendants from every loka — when Bhagavān is the object, the audience is universal.

The yajña-pavilion sounds like the streets of Vraja during a festival — mṛdaṅgas, paṭahas, conchshells, voices of sūtas and māgadhas, sweet-voiced Gandharvīs singing with their husbands. Vasudeva's sacrifice is staged as a saṅkīrtana before the word existed: the air itself becomes part of the offering.
