If we awake our consciousness in the astral plane, will we have to go to hell anyway after we die, once we reach our 108th death?
The only way to change our relationship with hell is by eliminating the psychological elements that trap our consciousness there.
If one successfully eliminates the ego and has the solar bodies, the consciousness is liberated and awakened. Because their inner hells are empty, they are awakened in the internal worlds. For them, meditation is effortless, spontaneous. They cannot die "unconsciously," since they are fully 100% awake.
All of this is because: if one successfully eliminates the entire ego and has the solar bodies, one has completed the second mountain and is a resurrected master.
Every experience —whether in a body or out of a body (ie. in heaven or hell) — is the exact outcome of cause and effect. Hell and devolution are simply the mechanical result of mistaken actions: the more severe the accumulated consequences, the more severe the mechanical process that responds.
They would simply be a very pure elemental. To become a human being, one must create the solar bodies, then perfect them.
