“Enq: What becomes of the other, the lower Skandhas of the personality, after the death of the body? Are they quite destroyed?
Theo: They are and yet they are not – a fresh metaphysical and occult mystery for you. They are destroyed as the working stock in hand of the personality; they remain as Karmic effects, as germs, hanging in the atmosphere of the terrestrial plane, ready to come to life, as so many avenging fiends, to attach themselves to the new personality of the Ego when it reincarnates.
Enq: This really passes my comprehension, and is very difficult to understand.
Theo: Not once that you have assimilated all the details, For then you will see that for logic, consistency, profound philosophy, divine mercy and equity, this doctrine of Reincarnation has not its equal on earth.
It is a belief in perpetual progress for each incarnating Ego, or divine soul, in an evolution from the outward into the inward, from the material to the Spiritual, arriving at the end of each stage at absolute unity with the divine Principle.
From strength to strength, from the beauty and perfection of one plane to the greater beauty and perfection of another, with accessions of new glory, of fresh knowledge and power in each cycle, such is the destiny of every Ego, which thus becomes its own Savior in each world and incarnation.”
