SB 3.13.33
tamala-nilam sita-danta-kotya
ksmam utksipantam gaja-lilayanga
prajñaya baddhañjalayo ’nuvakair
viriñci-mukhya upatasthur isam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Then the Lord, playing like an elephant, suspended the earth on the edge of His curved white tusks. He assumed a bluish complexion like that of a tamala tree, and thus the sages, headed by Brahma, could understand Him to be the Supreme Personality of Godhead and offered respectful obeisances unto the Lord.
