But whether the cause of these mysteries is to be found in jugglery, in some subtile connection between mind and matter, in animal magnetism, or in any other of the thousand new branches of natural or mental science, it must in the end be found--if found at all--to depend upon purely natural laws--laws fixed and undeviating in the very constitution of things, and which would have worked as well a thousand years ago as to-day. The supernatural is entirely excluded from the investigation, for that is a world beyond humanity's ken, into which no mortal may peer. If the world of disembodied spirits have any connection whatever with these wonderful and mystical phenomena, the question must ever remain as perplexing and mysterious as it is to-day. But human intellect is progressive. Age after age brings man nearer to the comprehension of the myriad wonders that surround him, though he must ever remain, while fettered to the earth and blinded by the body, unable to grasp and comprehend the Infinite. And the time will come, perhaps not in this age, nor even in its successor, when this perplexing problem shall be solved, and the hidden truths of to-day be as clear as the noonday sun. And if not here, then hereafter. Ah! that hereafter! how much of spiritual knowledge it involves! how much of manifestation of eternal truth and clearing up of mysteries! Into what a sea of knowledge does the spirit glide when it departs from the body! Every wave in that illimitable ocean of space is freighted with wisdom, every sound is the tone of undying truth, every breath is redolent of divine wisdom. We wonder now at the wisdom of the sages of our own and of ages gone by--at the learning, the profundity, the astonishing acquirements of the Newtons, the Lockes, the Bacons, the Franklins, and the Humboldts. But when we shall stand, in all the nakedness of pure, unfettered spirit, within the confines of the spirit land, and gaze with all the clearness of unveiled spiritual vision upon the wonderful mechanism of the universe and of the spirit world; when we see--as we shall see--laws and principles, and even abstract truths, as plainly as we now look upon the material objects around us; when, indeed, nothing shall be hidden from our view, and questions which are now too intricate for the wisest minds to solve, and others which are now too profoundly mysterious for human intellect to comprehend or even conceive, shall seem as axioms which need no argument, and which a child can perceive; when, finally, the mysteries of God himself are revealed to our progressive souls, then how contemptibly insignificant will appear the learning of the wisest of earth's sages! how infinitesimal the wisdom of Solomon himself! For to such knowledge we must and shall attain; knowledge wisely barred from our attainment in this earthly existence, lest in our presumption we should rebel against God, and, like Lucifer of old, endeavor to make
