XV. The Lord's Prayer: An Esoteric Study, Movement and Change an Essential Principle in the World of the Spirit, School of Turanian Adepts

The moment we no longer perceive with the senses, our inner life goes down into the indefinite sphere of darkness we call dreamless sleep today. The physical body and the ether body remain lying in the bed during sleep, the astral body goes outside. What is it in the human being which perceives the outside world? The astral body perceives colours and sounds. The astral body experiences pleasure when we enjoy something pleasurable and it feels pain as such. But this astral body cannot do anything in the human being today unless it is in a physical body, for it needs eyes, ears and all the physical tools to perceive the environment and also pleasure, pain, sorrow, joy, and so on. The physical body is just a tool, but it is necessary to today’s astral body. The moment the astral body is outside the physical body it no longer has perceptions.
