Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 15
Sanskrit:
तस्य त्रिभुवनाधीशा: फलदा: फलमिच्छताम् ।आत्मानं दर्शयां चक्रुर्माया विष्णुविनिर्मिता: ॥ १५ ॥
ITRANS:
tasya tribhuvanādhīśāḥphaladāḥ phalam icchatāmātmānaṁ darśayāṁ cakrurmāyā viṣṇu-vinirmitāḥ
Translation:
Demigods like Lord Brahmā and Lord Śiva, who can satisfy all materially ambitious men by giving them the rewards they desire, then manifested their own identities before King Rantideva, for it was they who had presented themselves as the brāhmaṇa, śūdra, caṇḍāla and so on.
