There is a great difference in the degrees of rapport existing between different people, and as the degree of success depends upon the degree of rapport it is of the greatest importance that you find some person with whom you are in harmonious vibration, in order to try these experiments in the Higher Phenomena.
We will not burden the student with recitals of experiments to perform in this Higher Phenomena demonstration. He may readily devise experiments for himself, from the examples given in connection with the Contact Mind Reading. The Transmitter may think of a card; an object; a name; a place; a scene; a thought; a feeling, etc., etc., without limit. And it makes no difference in the nature of the experiment or test, whether it be tried at long-range, or in the same room, without contact The feat is the same - the principle is the same.
As a further suggestion to the student, we would refer him to Lesson II (The Proofs Of Mind Reading) of this work, to the report of the experiments with Mr. Smith and Mr. Blackburn. If you will carefully read this report again, you will find a wealth of suggestions regarding the forms of demonstrations. But, bless your hearts, the experiments may be varied without end - the principle is the same in each case. The underlying principle is that the Transmitter thinks intently upon the appearance of the object or thing, or else upon the feeling connected with it if it be a feeling instead of an object; and the Receiver endeavors to receive the impression. The Transmitter manifests an Active Will to transmit the mental image, while the Receiver assumes a passive, receptive desire to receive the impression. The one is all Will - the other is all Desire.
Concluding this chapter on the Higher Phenomena of Mind Reading, we would say to the students that very few of them wilt have the perseverance to continue their experiments beyond the point of Contact Mind Reading, or perhaps the simplest forms of the Higher Phenomena. Contact Mind Reading is far more satisfactory to the average person, for its results are very constant indeed, and comparatively little labor, time and trouble are necessary to make the demonstrations. While on the contrary the results of the demonstrations of the Higher Phenomena are less constant except in the cases of very highly developed Receivers, working with Transmitters in almost perfect rapport and harmony. Then the average experiments along the lines of the Higher Phenomena, some days will prove highly successful, while other days will be almost barren of result. In fact there seems to be a sort of spontaneous action in the production of the Higher Phenomena, and the degree of success depends more or less upon some conditions of the mental world, not as yet fully understood by science. But to those who wish to push into the Unknown as far as they may do so, this field of the Higher Phenomena of Mind Reading offers a fascination and attraction difficult to express to those who have not experienced it.
