Akashic regression.

In the asetian bible it speaks of using meditation for "Akashic regression" now usually when the word akashic comes up it refers to the body. My question is (if) Akashic means the body does Akashic regression mean deaging the body? or did i misinterpret it ? if so, how?

A Sanskrit word meaning "sky", "space", or "aether" so wiki says......and it refers to the soul.......but I do not see how that would connect to the physical body more than a reference to the soul.....

thanks maxx ill be sure to correct.
