The soul is a natural denizen of the realm of light. It is a resident of the superconscious that exists outside of, but subsumes, the conventional three dimensions of space and time. It is not the realm of phenomenology, but of noumenology. It is the state of consciousness beyond waking, dreaming, and deep sleep. It is the state of what the yogis call turyia or the fourth state. It is from turyia that we unfold or descend or are involved in the involution of our world. It is to the state of turyia that we return in our evolution. We find ourselves captured and held prisoner by the curving gravity of these four dimensions that make us mortal, yet always in the deep fabric and essence of our existence we remember our abode in the trans-temporal and the trans-spatial realms of a far grater luminous reality.

Kant’s Transcendental Ego is an attempt to bridge the historic debate between empiricism and rationalism. All of our knowledge does comes from experiences (in the form of ‘phenomena’), but we possess an a priori 'nounmenal’ self which is a 'necessary precondition’ for having any experience at all.
