Mbh 14.35.5a

"'"The preceptor said, 'All this was declared (in days of old) by Brahma himself (the Grandsire of all the worlds). Applauded and practised by the foremost of Rishis, and depending on a knowledge of the Vedas, it involves a consideration of what constitutes the real entity. We regard knowledge to be the highest object, and renunciation as the best penance. He who, with certainty, knows the true object of knowledge which is incapable of being modified by circumstances, viz., the soul abiding in all creatures, succeeds in going whithersoever he wishes and comes to be regarded as the highest. That learned man who beholds the residence of all things in one place and their severance as well, and who sees unity in diversity, succeeds in freeing himself from misery. He who does not covet anything and does not cherish the idea of mineness with regard to anything, comes to be regarded, although residing in this world, as identifiable with Brahman. He who is conversant with the truth about the qualities of Pradhana (or Nature), acquainted with the creation of all existent objects, divested of the idea of mineness, and without pride, succeeds, without doubt, in emancipating himself. Understanding properly that great tree which has the unmanifest for its seed sprout, and the understanding for its trunk, and high consciousness of self for its branches, and the senses for the cells whence its twigs issue, and the (five) great elements for its flower-buds, and the gross elements for its smaller boughs, which is always endued with leaves, which always puts forth flowers, and upon which all existent objects depend, whose seed is Brahman, and which is eternal,--and cutting all topics with the sharp sword of knowledge, one attains to immortality and casts off birth and death.
