Is not the soul on a path through many lifetimes and it evolves that way?
Yes, metaphysical insight or deep intuition reveals that to be the case.
Just like the body and personality change and evolve in their own way during this physical lifetime, the soul, or a metaphysical body, evolves through multiple lifetimes.
However, Spiritual Realization has no concern with the evolution of the soul. In fact, such concern becomes an obstacle. Any concern with “me”, whether it is “me” personality, “me” body, or “me” soul, is an obstacle for the simple reason that there is no such “me” to be found except as a practical concept and an ephemeral experience of individuality. Thus that concern with the soul’s future strengthens the ego’s sense of separation.
