When you refer to Spirit are you talking about the soul?
No. The Soul is something associated with “me”. Spirit is beyond “me” of any kind, physical or metaphysical.
In my definition, Spiritual Realization is not the creation, salvation, improvement or evolution of the soul.
Spiritual Realization is the realization of what we are: Spirit.
For the soul to evolve time is needed. A soul is an object in duality. Just like the physical body is.
Spiritual Realization is Timelessness. Spirit is non-dual.
Spiritual Realization is equal to the removal of the identification with the object of a false belief.
We do not become Spirit. We Are Spirit, we have just been confused until realization happens.
