What it takes to attain the Oversoul or "Higher-self"

[Unbound]

Funny, I thought the Oversouls exist first in their entirety and then through fragmentation or vibrational division individual experiences are 'discerned' in the totality.

The only thing I would add about your explanation here is that you have only included destructive things as being "difficult to accept", but honestly I think for some entities those things are easy to accept and what is difficult to accept is the light, loving, freely sharing self. Just my thoughts on the matter!
