It is said to be able to remove itself from the physical body and travel around on its own - for example during sleep or magical workings, although it retains a link to the physical body via an infinitely elastic "astral cord" (various esotericist schools are divided as to whether such a thing exists, although most seem to favour its existence). Not only bionts but also vecs have described having "out-of-body" or "astral projection" experiences.

Physicalist philosophers strenuously deny the existence of an astral body.
