Truth is infinite, as God is infinite, and apprehension of this divine fact does not rest upon evidential testimony. But comprehension entails the evidence of reason, and is necessary to the evolution of the human understanding. Such evidence forms a link between mystery and knowledge, and offers a means by which the maturing intellect of man may obtain a gradual conversion of mystery into knowledge. Desire must precede fulfilment. May[37] not the longing to penetrate ever further into mysteries not as yet, by reason of our imperfections, demonstrable to our intellects, be the pioneer of the discovery of truths now unknown, but which in the fulness of time will be given as the spiritual inheritance of all those who, being pure in heart, shall see God in a light of revelation that has kept pace through all ages with the evolution of mankind? In such a manner does it seem that the desire for proof of human immortality should be considered. It is difficult to conceive how, on the physical plane of existence, evidence of the survival of human individuality after death could be obtained. The results of modern psychical research would seem to show that it is possible for the spirit of a dead person to be temporarily reinvested with a physical form other than its own body, and to communicate by this means with living persons. It is suggested that a spirit can so control a living person as to direct[38] itself through him as a medium for some purpose not necessarily known to him. It is further suggested that, presupposing the survival of individual consciousness after death to be a fact, a disembodied spirit might so possess a living person with its influence as to become virtually reincarnate. It is known in ordinary life that the will of one person can so influence the thoughts of another as practically to annihilate his individuality, which, falling more and more completely beneath this dominating mental force, becomes finally a mere passive instrument of another's will. Is it not possible that this same domination of one personality over another, so often noticed in life, may be continued after death in an even more intense degree, and thus provide proof of the survival of individuality? Unfortunately, although such hypotheses have been supported by psychical evidence and phenomena seemingly confirmative of their truth, there has been as yet no positive assurance that this so-called proof of survival[39] of individual consciousness is not the result of telepathy either deliberately or innocently evoked from an extreme sensitiveness of the medium to the mental suggestions of those who desire to see the particular phenomena that are subsequently produced.
