3.22.20

yato 'bhavad viśvam idaṃ vicitraṃ saṃsthāsyate yatra ca vāvatiṣṭhate /
prajāpatīnāṃ patir eṣa mahyaṃ paraṃ pramāṇaṃ bhagavān anantaḥ //

20. That Lord of Prajapatis from whom this diverse universe sprang, on whom it stands supported and into whom it is withdrawn—that glorious and eternal Lord is my highest authority in this matter.
