Mbh 12.239.3b

[955] The body within which the knowledge dwells has no real existence. The body, therefore, is not the refuge of the knowledge. Primordial Nature (Prakriti) having the three attributes (of Goodness and Passion and Darkness) is the refuge of the knowledge which exists only in the form of a sound. The Soul also is not the refuge of the knowledge. It is Desire that creates the knowledge. Desire, however, never creates the three attributes.[956] The man of wisdom, capable of subduing his senses, beholds the seventeenth, viz., the Soul, as surrounded by six and ten attributes, in his own knowledge by the aid of the mind. The Soul cannot be beheld with the aid of the eye or with that of all the senses. Transcending all, the Soul becomes visible by only the light of the mind's lamp. Divested of the properties of sound and touch and form, without taste and scent, indestructible and without a body (either gross or subtile) and without senses, it is nevertheless beheld within the body. Unmanifest and supreme, it dwells in all mortal bodies. Following the lead of the preceptor and the Vedas, he who beholds it hereafter becomes Brahma's self. They that are possessed of wisdom look with an equal eye upon a Brahmana possessed of knowledge and disciples, a cow, an elephant, a dog, and a Chandala.[957] Transcending all things, the Soul dwells in all creatures mobile and immobile. Indeed, all things are pervaded by it.[958] When a living creature beholds his own Soul in all things, and all things in his own Soul, he is said to attain to Brahma. One occupies that much of the Supreme Soul as is commensurate with what is occupied in one's own soul by Vedic sound.[959] He that can always realise the identity of all things with his own self certainly attains to immortality.
