5.1.21

_*
bhagavān api manunā yathāvad upakalpitāpacitiḥ priyavrata-nāradayor aviṣamam abhisamīkṣamāṇayor ātmasam avasthānam avāṅ-manasaṃ kṣayam avyavahṛtaṃ pravartayann agamat //

21. And the worshipful Brahma accepted the worship duly offered by Manu. While Priyavrata and Narada were looking on with unperturbed eyes he retired to his abode which lies beyond the

range of word and thought, so that he may indulge himself in (the contemplation of) Brahman who is beyond the range of ordinary perception.
