184 THE LAW OF PSYCHIC PHENOMENA.
his mind and will upon the work in hand, and thus, un« knowingly, it may be, partially hypnotizes himself. The Christian scientist sits quietly by the patient and concentrates his mind, in like manner, upon the central idea of curing the patient. And, in either case, just in proportion to the ability of the operator to get himself into the subjective condition will he succeed in accomplishing his object, whether it is the production of the higher phenomena of mesmerism, or the healing of the sick by telepathic suggestion.
If, then, the passive, or subjective, condition of the agent is necessary for the successful transmission of telepathic suggestions or communications, or if it is the best condition for such a purpose, it follows that the more perfectly that condition is attained, the more successful will be the experiment. As before observed, the condition of natural sleep is manifestly the most perfectly passive condition attainable. It is necessarily perfect, for all the objective senses are locked in slumber, and the subjective mind is free to act in accordance with the laws which govern it. Those laws are, it is true, at present but little understood; but this much has been demonstrated, namely, that the subjective mind is controllable by the mysterious power of suggestion, and is always most active during sleep.
Theoretically, then, we find that the most perfect condition either for the conveyance or the reception of telepathic impressions or communications is that of natural sleep. The only question that remains to be settled is whether it is possible for the agent or operator so to control his own subjective mind during his bodily sleep as to compel or induce it to convey the desired message to the sub-consciousness of the patient. To settle this question, we must again have recourse to the record of the labors and researches of the London Society for Psychical Research. It might well be inferred that this power must necessarily be possessed, when we take into consideration the general law of suggestion, coupled with the fact that the subjective mind is perfectly amenable to control by auto-suggestion.
