According to Max Heindel, the etheric "double" serves as a medium between the astral and physical realms. In his system the ether, also called prana, is the "vital force" that empowers the physical forms to change. From his descriptions it can be inferred that, to him, when one views the physical during an out-of-body experience, one is not technically "in" the astral realm at all.[45]
Other experients may describe a domain that has no parallel to any known physical setting. Environments may be populated or unpopulated, artificial, natural or abstract, and the experience may be beatific, horrific or neutral. A common Theosophical belief is that one may access a compendium of mystical knowledge called the Akashic records. In many accounts the experiencer correlates the astral world with the world of dreams. Some even report seeing other dreamers enacting dream scenarios unaware of their wider environment.[46]
The astral environment may also be divided into levels or sub-planes by theorists, but there are many different views in various traditions concerning the overall structure of the astral planes: they may include heavens and hells and other after-death spheres, transcendent environments, or other less-easily characterized states.[4
