• hṛṣīkeśam — Lord Kṛṣṇa, master of the senses
  Compound: hṛṣīka (senses) + īśa (master). Cf. Gītā opening (1.21). Gauḍīyas: the senses' true master is the One who lent them; agra-pūjā of Hṛṣīkeśa is the senses turning back toward their owner — the seed-definition of bhakti (CC: hṛṣīkeṇa hṛṣīkeśa-sevanam).
• hārdam — the inner thoughts
  From hṛd (heart). The interior mood. Yudhiṣṭhira's reading is not telepathy — it is the sympathetic resonance of one bhakta's heart with another's. Gauḍīyas: hārda is the address-form of all true devotional communication.
• praṇaya — by love
  From pra + √nī (to lead forth). Praṇaya in rasa-śāstra is intimate love that has lost its formality. Yudhiṣṭhira's pūjā does not stay polite; the love leads him beyond ceremony.
• vihvalaḥ — overwhelmed
  From vi + √hval (to stagger). Bhakti-vihvala is a stock Gauḍīya state — the body trembles, the mind cannot hold itself. Yudhiṣṭhira here visibly enters the sāttvika territory the Bhāgavatam will describe in detail later.

When a host has guessed his guests' silent wish and acts on it, the room becomes liquid with feeling. Yudhiṣṭhira reads the assembly's hārda — its inner heart — and proceeds to worship Kṛṣṇa, no longer as a sequence-decision but as an outpouring; he is praṇaya-vihvala, overwhelmed by love.
