Srimad Bhagavatam Canto 10, Chapter 33, Text 19

SB 10.33.19

krtva tavantam atmanam
 yavatir gopa-yositah
reme sa bhagavams tabhir
 atmaramo ’pi lilaya
 
Translation: 
 
Expanding Himself as many times as there were cowherd women to associate with, the Supreme Lord, though self-satisfied, playfully enjoyed their company.
 
Purport: 
 
As Srila Visvanatha Cakravarti points out, it has already been explained that Lord Krsna is eternally free from all material desire, perfect on the platform of spiritual self-satisfaction.
