It is to this radiation of psychoplasm that we must look for the explanation of such a simple thing--and at the same time such a complex thing--as psychic atmosphere. Do we not all know the peculiar atmosphere which surrounds individuals and places? The phenomena associated with apparitions have been ascribed to the penetration of structure by violently liberated psychoplasm set free in moments of passion and bloody violence. There too is the clue to its physical source, for in some obscure way blood and the emanations from blood play a vital and important part in psychic matters. Under normal circumstances psychoplasm is dissipated and the liberated energy that animated it goes with it to return in the normal way of the cycle of life. Under other circumstances the psychoplasm retreats back into the mind whence it came, just as the materialized ectoplasm is reabsorbed into the body of the medium. The dangers latent in assuming all astral light phenomena to be “good” can be realized when it is considered what may occur to the projected psychoplasm which is emotionally liberated beyond the confines of the body and beyond its living human control. A party of some half-dozen form a circle in some provincial city. They may know one another well or they may be, comparatively speaking, strangers. However well they may know the public lives of the members of the circle, can they fathom the secret soul of each sitter? Can they say whose mind is a garden of purity or who may have some tendency to some unknown enormity? Yet it is precisely this weakness that makes a soul-appalling danger of the hideous mental promiscuity that is one of the essential things of which all the more ingenuous and simple believers and a few clever evil hypocrites among Spiritualists make a cult. They may unknowingly include among themselves an individual, man or woman, who has somewhere a secret kink--a mental leaning--it need not be an actually accomplished physical fact--but simply an inclination to the obscene, the evil, or the cruel. The circle launches its prayer, concentrates on the attraction of the discarnate spirits of those who have passed over--and what comes, who comes? There is no gifted Spiritualist or student of matters psychic who has not had either personal or absolutely credible second-hand experience of the existence of bad or lying spirits. It is true that insistence upon their existence has latterly become unfashionable in Spiritualist circles--because it does harm to the professional medium, but not even the most insistent of suppressive propaganda can live down the writings and testimonies of the past and the ever-recurrent undeniable phenomena of the present.
