Toward Ecosophy

In occult theory there are several different levels of nonphysical reality that human beings can experience and work with. There are various ways of talking about these; the system I use talks about the etheric, astral, and mental planes or levels. If I understand the Indian concept of prana correctly -- and I'll gladly accept correction if I don't! -- prana is the life force, which flows along the nadis and keeps the physical body alive; this is what occultists call the etheric level, the level of life force. The astral level is one step further from dense matter -- it's the level of dreams, imagination, and visions -- and that's the level on which the astral light operates. The astral light is the substance of the astral level, just as the life force/prana is the substance of the etheric level, and matter is the substance of the physical level.
