VIII. The existence and operation of occult laws and forces in nature which may be used to produce phenomenal results on this plane; that these laws and forces may be put into operation by the subconscious man and by the elementals either consciously or unconsciously, and that many of these occult operations are automatic in the same way as is the freezing of water under intense cold or the melting of ice under heat.
IX. That the Astral body of the medium, partaking of the nature of the Astral substance, may be extended from the physical body, may act outside of the latter, and may also extrude at times any portion of itself such as hand, arm, or leg and thereby move objects, indite letters, produce touches on the body, and so on _ad infinitum_. And that the Astral body of any person may be made to feel sensation, which, being transmitted to the brain, causes the person to think he is touched on the outside or has heard a sound.
Mediumship is full of dangers because the Astral part of the man is now only normal in action when joined to the body; in distant years it will normally act without a body as it has in the far past. To become a medium means that you have to become disorganized physiologically and in the nervous system, because through the latter is the connection between the two worlds. The moment the door is opened all the unknown forces rush in, and as the grosser part of nature is nearest to us it is that part which affects us most; the lower nature is also first affected and inflamed because the forces used are from that part of us. We are then at the mercy of the vile thoughts of all men, and subject to the influence of the shells in _Kama Loka_. If to this be added the taking of money for the practice of mediumship, an additional danger is at hand, for the things of the spirit and those relating to the Astral world must not be sold. This is the great disease of American spiritualism which has debased and degraded its whole history; until it is eliminated no good will come from the practice; those who wish to hear truth from the other world must devote themselves to truth and leave all considerations of money out of sight.
To attempt to acquire the use of the psychic powers for mere curiosity or for selfish ends is also dangerous for the same reasons as in the case of mediumship. As the civilization of the present day is selfish to the last degree and built on the personal element, the rules for the development of these powers in the right way have not been given out, but the Masters of Wisdom have said that philosophy and ethics must first be learned and practised before any development of the other department is to be indulged in; and their condemnation of the wholesale development of mediums is supported by the history of spiritualism, which is one long story of the ruin of mediums in every direction.
