The astral body is the body you will take with you when you die.

The astral body is the body you will take with you when you die. The greater the quantity of astral energy, the higher stage of evolution you will be reborn into. You can't have any faith in your body, mind, or emotions surviving death. Only your consciousness, your awareness, has this potential. The astral body is the vehicle that carries it until liberation, and the re-union with everything, everywhere, takes place. This is when you experience the Divine Body and live happily ever after.
