The only way for a Personality to gain immortality, at least for the time being, like the Ego, is to direct all experience, love and compassion into the memory of the Jiva
The Ethereal and Astral Bodies dissolve already on the 9th day after physical death and the human Soul rises to the Mutable Layer, which is the World of the Mind, where it remains for up to 40 days
In this Layer there is an understanding of the Cosmic Task and the level of fulfillment of the duties assigned to it, and also a decision is made whether the experience of the Personality will be left in the memory of Jiva
If the experience of the Personality does not correspond to the Tasks of the incarnation, as a result of the egocentricity of the Personality, everything experienced is erased along with the collapse of the Causal and Mental Bodies
