• uttamaḥ - śloka — the glorious Lord, He whose fame is sung in the best verses
  Uttama (highest) + śloka (verse, praise). One of the Bhāgavatam's signature names for Kṛṣṇa, used here precisely because the deliverance about to be related is itself worthy of śloka. The name does the work the verse describes.
• kara - abhimṛṣṭaḥ — touched by the hand
  Kara (hand) + abhimṛṣṭa (well-touched, caressed). Sparśa with Kṛṣṇa's hand is purificatory in the Bhāgavatam — Pūtanā touched His foot, Aghāsura His entry, this lizard His palm. Gauḍīyas hold sparśa as a recognised mode of deliverance.
• santapta - cāmīkara - caru - varṇaḥ — complexion the colour of molten gold
  Santapta (molten) + cāmīkara (gold) + cāru (beautiful) + varṇa (colour). The form that emerges is svargī-grade. Gauḍīya commentators note the poet's restraint: he describes the demigod beautifully but withholds Kṛṣṇa's own description until the contrast lands.
• svargī — a resident of heaven
  From svarga. The lizard-form belonged to a former svargī. The chapter's whole engine: even residence in svarga is not safe from a brāhmaṇa-aparādha. The fall from heaven follows; only Kṛṣṇa's touch reverses it.

• What 'lizard form' of mine — old karma, old habits — am I still inhabiting when Kṛṣṇa has already touched me?
• How would living as the spiritually-touched being I already am change today?

A lizard touched by Kṛṣṇa's hand becomes a golden demigod in an instant — proof that the form fixed by karma is not the soul's address but its costume, and one touch of Bhagavān can change the costume back. The body is loaned; the touch is real.
