No sensible person should surrender himself to the magnetic influence of a human being of whom he knew nothing; he should need to know and have confidence in him before doing so; yet we find many who, impelled by a desire to be a medium, without understanding how much the word implies, sit down and invite any magnetizer who comes along to experiment upon him. Under such circumstances, nothing but a high motive and a pure purpose will protect them from the operations of unwise or mischievous intelligences. As well might they go and sit in a public place with their eyes blindfolded, and with an inscription on their breasts, 'Who will come and magnetize me?' * * Mesmeric influence from an experienced operator, for the purpose of inducing susceptibility, is sometimes helpful to a sensitive. If the mesmerist can put you in the trance condition and then hand you over to trustworthy spirits to control you, well and good. In the same way, mesmeric passes may be helpful in the liberation of your clairvoyant powers. The operator may succeed in throwing you into the deep trance state, in which you may travel or become clairvoyant, but we would not recommend you to submit to mesmeric influence or hypnotic suggestions from anyone, unless you know that he is experienced and a thoroughly honorable and trustworthy individual. In circles for development one member is frequently impressed, or controlled to make magnetic passes over another to aid in his unfoldment; and if such a thing should happen to you, and the influence is congenial, there need be no objection raised by you; but beware of those people who claim to be able, by mesmerism, to develop you into a medium in a given period of time.

In too many cases, only the power of auto-hypnotism is manifested, and we have obsession, fraud and folly as the result. There is one sure method of detecting the auto-hypnotic trance, and showing the difference between that and the genuine spirit trance. Any competent magnetist or hypnotiser can throw off the spell in all cases of self-induced trance, unless it has reached the condition of complete catalepsy. But if a spirit has induced the trance and controls the medium, it will laugh at the hypnotist's efforts to restore him to the ordinary condition. The most unfortunate feature of this sorry business is that the poor subject is self-deceived, and imagines that he is a full-fledged medium; and when he has made some terrible break on the platform or elsewhere he shields himself by laying all the responsibility upon some supposed spirit guide.

Psychic Sponges.

There are some people who, when they sit in a circle, are extremely helpful, and give off the right kind of force that readily blends with that of the sensitive; but there are others who draw upon and appropriate the psychic forces which are needed by the medium, or by the spirits through the medium. While they mean well, enjoy the seances, and feel 'SO much better' after them, the success of the circle is endangered so far as the object for which it was formed is concerned. Such persons are 'psychic sponges,' and should be requested to sit outside the circle, or be asked kindly to refrain from attending.

The medium must keep a level head and proceed cautiously. He should never allow any spirit, in or out of the body, to usurp his right of private judgment or exercise any undue authority over him. Eternal vigilance is the price of liberty; you must use your own discretion and try the spirits before you trust to them.

In a developing circle many things can be tolerated, because both sides are experimenting and 'feeling their way towards each other,' and it is difficult at first to know just what is necessary or possible. But it is a safe rule to follow for one to refuse to be dictated to by the spirits and to decline to go on blindly.

Do not always be ready to be controlled, or to drop into a trance just because you 'feel the influence,' and 'a spirit wants to say something,' or to oblige injudicious friends who 'wish you would let him come.' Many people are very inconsiderate, and although they do not SAY so, they THINK (and the sensitive FEELS their thought) 'I do wish he would go under control and tell me something.' You should decline to be controlled EXCEPT at the times when you voluntarily and with set purpose lay yourself open to the influence of the spirits, in a properly constituted circle, or when you are prepared for it. If the spirits cause you to do foolish or ridiculous things, gently but firmly refuse to again submit. Do not be induced to yield by promise of future greatness and success. Not a few people have had their vanity tickled and their ambitions aroused by the flattery of crafty and domineering spirits, and in consequence they have been misled into doing and saying very absurd and foolish things.
