"Quantum level is the doorway to God. To go through the door isn't something we choose; participation is mandatory. In India the soul has two parts. One is called [Jiva] which corresponds to the individual soul making its long journey through many lifetimes until it reaches full realization of God. Jiva is involved in action. It is affected by our good and bad acts; it rules our conscience. and all the seeds of Karma. The kind of person you turn out to be is rooted in Jiva. The kind of life you make will change Jiva everyday.

The second half of the soul is called [Atman], does not accompany us on the journey. It is pure spirit, made of the same essence as God. Atman cannot change in any way. It never reaches God because it never left in the first place. No matter how good or bad your life, the Atman remains constant."
