Mbh 14.47.1a

"'"'Brahma said, "The ancients who were utterers of certain truth, say that Renunciation is penance. Brahmanas, dwelling in that which has Brahman for its origin, understand Knowledge to be high Brahman.[143] Brahman is very far off, and its attainments depends upon a knowledge of the Vedas. It is free from all pairs of opposites, it is divested of all qualities; it is eternal; it is endued with unthinkable qualities: it is supreme. It is by knowledge and penance that those endued with wisdom behold that which is the highest. Verily, they that are of untainted minds, that are cleansed of every sin, and that have transcended all passion and darkness (succeed in beholding it). They who are always devoted to renunciation, and who are conversant with the Vedas, succeed in attaining to the supreme Lord who is identical with the path of happiness and peace, by the aid of penance. Penance, it has been said, is light. Conduct leads to piety. Knowledge is said to be the highest. Renunciation is the best penance. He who understands self through accurate determination of all topics, which is unperturbed, which is identical with Knowledge, and which resides in all entities, succeeds in going everywhere. The learned man who beholds association, and dissociation, and unity in diversity, is released from misery. He who never desires for anything, who despises nothing, becomes eligible, even when dwelling in this world, for assimilation with Brahman. He who is conversant with the truths about qualities of Pradhana, and understands the Pradhana as existing in all entities who is free from mineness and egoism, without doubt becomes emancipated. He who is freed from all pairs of opposites, who does not bend his head to any body, who has transcended the rites of Swadha, succeeds by the aid of tranquillity alone in attaining to that which is free from pairs of opposites, which is eternal, and which is divested of qualities.
