Mbh 14.47.1b

Abandoning all action, good or bad, developed from qualities, and casting off both truth and falsehood, a creature, without doubt, becomes emancipated. Having the unmanifest for the seed of its origin, with the understanding for its trunk, with the great principle of egoism for its assemblage of boughs, with the senses for the cavities of its little sprouts, with the (five) great elements for its large branches, the objects of the senses for its smaller branches, with leaves that are ever present, with flowers that always adorn it and with fruits both agreeable and disagreeable always produced, is the eternal tree of Brahman which forms the support of all creatures. Cutting and piercing that tree with knowledge of truth as the sword, the man of wisdom, abandoning the bonds which are made of attachment and which cause birth, decrepitude and death, and freeing himself from mineness and egoism, without doubt, becomes emancipated. These are the two birds, which are immutable, which are friends, and which should be known as unintelligent. That other who is different from these two is called the Intelligent. When the inner self, which is destitute of knowledge of nature, which is (as it were) unintelligent, becomes conversant with that which is above nature, then, understanding the Kshetra, and endued with an intelligence that transcends all qualities and apprehends everything, one becomes released from all sins."'"'"
