“ ‘My dear Lord, You are very affectionate to Your devotees. You are also a truthful and grateful friend. Where is that learned man who would give You up and surrender to someone else? You fulfill all the desires of Your devotees, so much so that sometimes You even give Yourself to them. Still, You neither increase nor decrease by such activity.’
This is a verse from Śrīmad-Bhāgavatam (10.48.26).
