"Bhishma said, 'All immobile and mobile beings, distributed into four classes, have been said to be of unmanifest birth and unmanifest death. Existing only in the unmanifest Soul, the Mind is said to possess the attributes of the unmanifest. As a vast tree is ensconced within a small unblown Aswattha flower and becomes observable only when it comes out, even so birth takes place from what is unmanifest. A piece of iron, which is inanimate, runs towards a piece of loadstone. Similarly, inclinations and propensities due to natural instincts, and all else, run towards the Soul in a new life. Indeed, even as those propensities and possessions born of Ignorance and Delusion, and inanimate in respect of their nature, are united with Soul when reborn, after the same manner, those other propensities and aspirations of the Soul that have their gaze directed towards Brahma become united with it, coming to it directly from Brahma itself. Neither earth, nor sky, nor heaven, nor things, nor the vital breaths, nor virtue and vice, nor anything else, existed before, save the Chit-Soul. Nor have they any necessary connection with even the Chit-Soul defiled by Ignorance. The Soul is eternal. It is indestructible. It occurs in every creature. It is the cause of the Mind. It is without attributes, This universe that we perceive hath been declared (in the Vedas) to be due to Ignorance or Delusion. The Soul's apprehensions of form, etc., are due to past desires.
