If an individual, who has not as yet reached the stage of psychical and spiritual discernment whereby he is given the evidence of the higher sense on the question of the survival of the soul, finds his reason demanding something akin to proof, let him turn his mental gaze inward instead of outward, and there he will find that which he seeks. For, at the last, as all philosophy teaches us, the world of the inner is far more real than is the world of the outer phenomena. In fact, man has no actual knowledge of the outer—all he has is the report of the inner upon the impressions received from the outer. Man does not see the tree at which he is gazing—he perceives but the inverted image of that tree pictured upon his retina. Nay, more, his mind does not even see this image, for it receives only the vibratory report of the nerves whose ends have been excited by that image. So we need not be ashamed of taking mental stock of the inner recesses of our mind, for many of the deepest truths are recorded there.
