Brihad Bhagavatamrta
Part 2 Chapter 1 Text 15

tatra sri-krsna-padabja-
saksat-seva-sukham sada
bahudhanubhavantas te
ramante dhik-krtamrtam

TRANSLATION
The pure devotees living in Vaikuntha enjoy forever in varied ways the happiness of directly serving Sri Krsna’s lotus feet. In comparison, the nectar of liberation appears condemned.
