I will admit that I have not stated what others should do, but in explaining what I have done I mean to explain what general course others will have to pursue. By taking into consideration what I have said, and adding thereto what I shall still have to say, a general idea may be formed of what the reader must do to place himself in a position to make original observations by means of introspection. No two cases being just alike, from the fact that heredity, the mental capacity, physical condition, education, temperament, nationality, etc., with no two persons are just alike, it is not well possible to point out a course quite suitable to all. I might as well attempt to arrive at a law by the observance of which _all_ persons would be enabled to write poetry. Still, needing assistance in this vast undertaking, I am particularly anxious to make this matter clear, as the results of these observations are of vital interest to all, and I am but one weak, ignorant mortal creature, with but a small fraction of a life left to me in which to state that which it would at least take a full lifetime to properly and fully explain. I am overburdened with an insight which is being increased daily, even against my will, and which I shall never be able to fully communicate to others. Let the flood-gates of truth once be opened and come in upon you as they have upon me, and you will be overwhelmed by the mass of their detail no less than by the vigor of their mass. My great want, therefore, for the purpose of more fully arriving at these facts and obtaining ever higher results is assistance and coöperation. I wish it to be distinctly understood, however, that I do not mean this in a personal sense--far from it; but in the interest and the promotion of science, as everybody wanting to make original observations must pursue these studies for himself and by himself. Why such a course has not been heretofore pursued by others I am at a loss to understand, except from the fact that it takes an unusual amount of perseverance to reach the first results. Though _all_ persons may not be able to personally obtain satisfactory results, _all_ may be _benefited_ by the results obtained by those qualified to successfully carry on a course of observations by means of introspection. The world at large will always have to be satisfied with being simply the beneficiary of scientific research; more especially of research in matters spiritual or psychical. From facts thus obtained rules may be deduced, which, translated into "physical forms," may become the property of all. In this manner numerous observations I have made have already assumed a practical shape; but I have not as yet been able to devote the necessary time to them to produce a system which may be used for general instruction.
