The soul is enshrouded in a fluidic body called the Astral Body. The Astral Body is similar to the physical body. Within the Astral Body is the soul with its mind, with its will, with its conscience, with its feelings. Thus, the Astral Body is marvelous; this is the soul’s body.
When the flesh and bone body is asleep, the soul leaves the flesh and bone body and wanders all over. The soul voyages in its Astral Body.
When King Nebuchadnezzar lay sleeping in his bed, he thought about what he would be in the future; then he fell asleep. The King’s soul then left the flesh and bone body, traveled in the Astral Plane, and saw a statue whose head was of gold, its breast and arms were of silver, its legs were of iron, and its feet were partly iron and partly baked clay.
