Mbh 12.319.7a

"'Bhishma continued, "Thus instructed by the intelligent Yajnavalkya the king of Mithila became filled with joy. The king honoured that foremost of ascetics by walking round his person. Dismissed by the monarch, he departed from his court. King Daivarati, having obtained the knowledge of the religion of Emancipation, took his seat, and touching a million of kine and a quantity of gold and a measure of gems and jewels, gave them away unto a number of Brahmanas. Installing his son in the sovereignty of the Videhas, the old king began to live, adopting the practices of the Yatis. Thinking mainly of all ordinary duties and their derelictions (as laid down in the scriptures), the king began to study the science of the Sankhyas and the Yogins in their entirety. Regarding himself to be Infinite, he began to reflect on only the Eternal and Independent One. He cast off all ordinary duties and their derelictions, Virtue and Vice, Truth and Falsehood, Birth and Death, and all other things appertaining to the principles produced by Prakriti. Both Sankhyas and Yogins, agreeably to the teachings of their sciences, regard this universe to be due to the action of the Manifest and the Unmanifest. The learned say that Brahma is freed from good and evil, is self-dependent, the highest of the high, Eternal, and Pure. Do thou, therefore, O monarch, become Pure! The giver, the receiver of the gift, the gift itself, and that which is ordered to be given away, are all to be deemed as the unmanifest Soul. The Soul is the Soul's one possession. Who, therefore, can be a stranger to one? Do thou think always in this way. Never think otherwise. He who does not know what is Prakriti possessed of attributes and what is Purusha transcending attributes, only he, not possessed as he is of knowledge, repairs to sacred waters and performs sacrifices. Not by study of the Vedas, not by penances, not by sacrifices O son of Kuru, can one attain to the status of Brahma.
