sa vai bhagavataḥ śrīmat
pāda-sparśa-hatāśubhaḥ
bheje sarpa-vapur hitvā
rūpaṁ vidyādharārcitam
saḥ — he; vai — indeed; bhagavataḥ — of the Supreme Personality of Godhead; śrī-mat — divine; pāda — of the foot; sparśa — by the touch; hata — destroyed; aśubhaḥ — all inauspiciousness; bheje — assumed; sarpa-vapuḥ — his snake body; hitvā — giving up; rūpam — a form; vidyādhara — by the Vidyādharas; arcitam — worshiped.
The snake had all his sinful reactions destroyed by the touch of the Supreme Lord’s divine foot, and thus he gave up his serpent body and appeared in the form of a worshipable Vidyādhara.
The words rūpaṁ vidyādharārcitam indicate that the erstwhile snake appeared in a beautiful form worshipable among the demigods called Vidyādharas. In other words, he appeared as the leader of the Vidyādharas.
