• svairam — at Their will, freely
  Adverb from sva + īra. By Their own pleasure. Gauḍīya: Kṛṣṇa moves svairam — His every motion is independently willed, not driven. The bhakta's ideal is to come within range of this svaira-līlā.
• ādityaḥ — the sun
  From √ad — to eat (the sun consumes darkness). Setting suns frame Kṛṣṇa's days in Canto 10. Gauḍīya note: even sūrya is just a lamp in Bhagavān's drama — sun rises and sets to mark His scenes.
• kṛṣṇa-rāmau — Kṛṣṇa and Balarāma
  Contiguous compound dual. The brothers' joint name. Gauḍīya: kṛṣṇa-rāma is itself a mantra-pair (Rāmādi-mūrtiṣu kalā-niyamena tiṣṭhan, Brahma-saṁhitā 5.39) — the same Bhagavān in two simultaneous forms.
• gopaiḥ — by the cowherd boys
  Instrumental plural of gopa. The sakhās are still with Him — Mathurā has not severed Vraja. Gauḍīya emphasis: gopa-saṅga is not abandoned even in the killing-week of the demon.
• śakaṭam — the wagons, the encampment
  From √śak — that which carries. The śakaṭa is the cowherd's caravan. Gauḍīya parallel: the same word used for the cart Kṛṣṇa kicked over as an infant (Śakaṭāsura, SB 10.7) — the Bhāgavata's vocabulary keeps returning to the cowherd's domestic geometry.

Two princes who have toured a strange city all afternoon return at dusk to the wagons of their fathers' camp — the day's work done, the night ahead's larger work undisclosed. Kṛṣṇa keeps the rhythm of an ordinary cowherd day even on the eve of His most consequential combat.
