Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 4

Sanskrit:

न खलु गोपीकानन्दनो भवान्अखिलदेहिनामन्तरात्मद‍ृक् ।विखनसार्थितो विश्वगुप्तयेसख उदेयिवान् सात्वतां कुले ॥ ४ ॥

ITRANS:

na khalu gopīkā-nandano bhavānakhila-dehinām antarātma-dṛkvikhanasārthito viśva-guptayesakha udeyivān sātvatāṁ kule

Translation:

You are not actually the son of the gopī Yaśodā, O friend, but rather the indwelling witness in the hearts of all embodied souls. Because Lord Brahmā prayed for You to come and protect the universe, You have now appeared in the Sātvata dynasty.

Purport:

The gopīs here imply, “Since You have descended to protect the entire universe, how can You neglect Your own devotees?”
