3.2.5

samprāpyainam ṛṣayo jñānatṛptāḥ kṛtātmāno vītarāgāḥ praśāntāḥ.
te sarvagaṃ sarvataḥ prāpya dhīrā yuktātmānaḥ sarvam evāviśanti.

5. Attaining Him, the seers (*ṛṣi*) who are satisfied with knowledge,
Who are perfected souls (*kṛtātman*), from passion free (*vīta-
rāga*), tranquil—
Attaining Him who is the universally omnipresent, those wise,
Devout souls (*yuktātman*) into the All itself do enter.
