Śrīmad-Bhāgavatam · Text 10.32.20
Who is speaking and story frame
नाहं तु सख्यो भजतोऽपि जन्तून्
भजाम्यमीषामनुवृत्तिवृत्तये ।
यथाधनो लब्धधने विनष्टे
तच्चिन्तयान्यन्निभृतो न वेद ॥ २० ॥
nāhaṁ tu sakhyo bhajato ’pi jantūn
bhajāmy amīṣām anuvṛtti-vṛttaye
yathādhano labdha-dhane vinaṣṭe
tac-cintayānyan nibhṛto na veda
But the reason I do not immediately reciprocate the affection of living beings even when they worship Me, O gopīs, is that I want to intensify their loving devotion. They then become like a poor man who has gained some wealth and then lost it, and who thus becomes so anxious about it that he can think of nothing else.
