Sūta said: Hence, one shall always practise perfect knowledge having that as the foundation and the ultimate goal. O leading brahmins, a yogin who is satiated with knowledge alone and who has eschewed all contacts with worldly objects has no further duty. If he has, he is no longer a knower of reality. Neither in this world nor in the other has he any duty,[32] since he is a liberated soul. Hence, the knower of Brahman is the knower of the reality of perfect knowledge and perpetually engaged in the practice of perfect knowledge. He eschews the practice of all duties. He obtains perfect knowledge alone. O excellent brahmins, if one who takes pride in his position in varṇāśrama (as Brāhmin, kṣatriya, etc.) takes pleasure in other things (other than Brahman) certainly he is deluded and ignorant, even though he might have discarded anger. Ignorance is the cause of worldly existence and adoption of physical bodies means worldly existence.
