I have come across the writings of Phillip Goddard, who suggests that all spiritual beliefs in chakras, auras, God, goddesses, religions new age or otherwise, rituals, E.T's, ghosts, entities, paranormal activity, astral projection and more are tricks/illusions which are actually thought forms, which interact and feed off of mind of conscious beings.The purpose of these things are to keep us distracted from our true nature as fundamental consciousness, which is all there is, or the ultimate. He calls it the metaspace in which all arises and dissolves. Furthermore the belief in a soul is also from this "garbage" and can lead to unnecessary and unhealthy physical incarnations. These thought forms/illusions collect in the astral sub reality, as he calls it which is different from fundamental consciousness, and are distortions of consciousness, and plague all of existence.
He explains how it came about here:
He says that the only safe way(to his knowledge) to clear out the astral sub reality is by using a set of affirmations which he came up with. As well as some yogic exercises and using what he calls a clarity sphere in order to dissolve/weaken the garbage. Apparently crystals, which new agers use for energy cleansing and healing are actually harmful. I have used some of his affirmations and have noticed a difference but am no longer actively doing so, but I do feel he may be on to something.
He insists this is not a belief, nor does he want anyone to believe in it, but it rather a working model that he has found to be effective in understanding whats going on.
