• māsyasya — the child only a few months old
  Genitive of māsya (one of a few months). Bhāgavatam dates each demonic encounter — three months for Śakaṭa, one year for Tṛṇāvarta — because the chronology underscores the implausibility and so the divinity.
• caraṇau — His two feet
  Dual of caraṇa — sacred feet. The gopas list the toe-strike almost casually; but caraṇa-kamala is the highest object of bhakti, and a kick from these feet is itself the gift of liberation to Śakaṭāsura.
• anaḥ — the cart
  Anaḥ — bullock cart. Hostile to the infant, it housed an asura. Gauḍīya commentators read every Vraja demon as a former resident liberated through enmity (vairānubandha) — even the cart attains release.
• viparyastam — turned upside-down
  Vi- + paryasta — overturned, inverted. The cart's overturning is also an allegorical inversion: what looked like the threat to the child was undone by the child it threatened.
• prapada — by the tip of the foot
  Prapada — the very tip of the toe. The cosmos shaken by a toe-tip is the Bhāgavatam's recurring sign of svayaṁ-bhagavān; Brahmā contemplates these feet, Mahā-deva carries them on his head.

  His Grace Padaseva Prabhu· Oriya

A potter's heavy cart, loaded with vessels, rests on a sleeping child's feet — and a single twitch of the toe overturns the whole thing. Kṛṣṇa kicks not in anger but in the half-conscious motion of an infant; the cart, an asura in disguise, falls because the foot it touched is the foot of all worlds.
