• brahma-ādayaḥ — Brahmā and others
  Compound: brahmā + ādayaḥ (and so on). Brahmā heads the list of celestial spectators — appropriate, since vv. 35–36 of this chapter will name him as Bhagavān's dhiṣaṇā (intelligence). The grandfather of the universe attends to learn the grammar of subordination.
• siddha-cāraṇāḥ — Siddhas and Cāraṇas
  Compound: siddha (perfected beings, masters of mystic siddhi) + cāraṇa (celestial bards). Gauḍīyas note that even those who have attained the eightfold siddhis come merely to watch — siddhi is for spectating; bhakti is for participating.
• vimānaiḥ — in celestial airplanes
  Instrumental plural of vimāna. The vimāna is the standard Purāṇic vehicle of devas; the verse stresses that this battle is staged for the upper realms to witness, not concealed — Bhagavān's victories are public theology.
• draṣṭum — to see
  Infinitive of √dṛś. Darśana — the same word that names the goal of every Vaiṣṇava pilgrimage. Bhagavān always provides darśana, even in the form of a battlefield; the upper worlds know this and come for it.

  His Grace Padaseva Prabhu· Oriya

• What detail of Kṛṣṇa's pastimes have I been treating as background that the demigods would gather to witness?
• How would my hearing change if I imagined heaven watching alongside me?

When two great kings prepare to meet on a field, every wise man in the kingdom postpones business to watch. Brahmā, the sages, the Siddhas — the heavens empty into airplanes because the question being settled below is not 'who will win' but 'what is the order of the worlds'.
