after moksha when the soul goes back up to god is its energy dissipated and dissolved into the collective, or is it like a piece of a puzzle that fits and even though it is part of the entire sea of energy it still remains indivisible?
Neither. There is no such thing as an invisible, eternal soul that leaves the body at death. The immortality of the human soul, taught by most religions, is not a Bible teaching. Rather, when God formed the first man from the dust from the ground, and blew into his nostrils the breath of life, the man "
came to be a living soul". (Genesis 2:7) After Adam sinned, God told him "you [will] return to the ground, for out of it you were taken For dust you are and to dust you will return." (Genesis 3:18)
The Bible clearly teaches that the soul can and does die. (Ezekiel 18:4,20)
The hope for the dead is a return to life or resurrection. If we had a soul that never dies, the resurrection would not be necessary.
This means the teachings of hellfire, eternal torment, and reincarnation are all alike false teachings and have no basis in reality.
