padav asya vinirbhinnau
lokeso visnur avisat
gatya svamsena puruso
yaya prapyam prapadyate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thereafter the legs of the gigantic form separately became manifest, and the demigod named Visnu [not the Personality of Godhead] entered with partial movement. This helps the living entity move to his destination.
