SB 12.12.56
yuyam dvijagrya bata bhuri-bhaga
yac chasvad atmany akhilatma-bhutam
narayanam devam adevam isam
ajasra-bhava bhajatavivesya
Translation:
O most eminent of brahmanas, you are all indeed extremely fortunate, since you have already placed within your hearts Lord Sri Narayana — the Personality of Godhead, the supreme controller and the ultimate Soul of all existence — beyond whom there is no other god. You have undeviating love for Him, and thus I request you to worship Him.
