Evil entity

Let us imagine that a man has a common evil desire, but makes no attempt to realize it on the physical plane. He only draws his dark desire on the astral plane, and so creates a kind of 'entity', by condensing the astral according to his intention. This artificial 'being' does not a physical body, but it is a kind of astrosome, and its correspondence to the human monad (spirit) is just the mental idea of the evil intention or wish. Such a being - according to the property of its 'monad' - can act and influence only in one direction as intended by its unwise creator, man, who is usually unaware of his foolishness.
Now, on whom will the influence of such a demon be exerted? Yes, firstly on the father of it himself, the draughtsman who created the astral picture of the evil deed. We will call this type of ominous artificial entity a larva. Such a larva will watch its 'father' in order to prevent him from forgetting his evil intentions and desire, and to fortify the larva's life by new meditations about the same theme. But it can also attach itself to another man, who has certain astral and mental affinity with the first one. We then say that a larva has left one man and fastened itself (like a leech) to another.http://web.archive.org/web/20050204065037/http://rvmagic.com/tarot/Larva.htm
