4 . INTERIOR VISION. we are all imperfect; but no other being can occupy your or my ground, or be so great in our respective directions as we are. No one exactly is like us, — we precisely like nobody. We are like the world, —green spots and deserts,— arid here, frozen there,— fertile in one spot, sterile in another; therefore we should cultivate our special loves! Clairvoyant vigor demands attention to the law: “The eternal equation of vital vigor is, Rest equals exercise.” Remember this, and retain your power. Clairvoyance is an affair of the air, food, drink, love, passion, light, sleep, health, rest, sunshine, joy, music, labor, exercise, lungs, liver, blood, quite as much as of mesmerism and magnetic coma, for all mental operations are physically conditioned.

It has been the study of my life, and that knowledge, which enables me to demonstrate the laws governing it, and by which it may be developed, also enables me to understand and impart those which attend its aberrant phenomena. ‘This mystic ground has hitherto been the prolific hot-bed of a host of noxious, dangerous superstitions and quackeries ; and I believe my own is the first attempt to reclaim it to rational investigation. Clairvoyance is a generic term, employed to express various degrees and modes of perception, whereby one is enabled to cognize and know facts, things, and principles; or to contact certain knowledges, without the use, and independent of, the ordinary avenues of sense. It is produced or attained in various degrees, by different methods, and is of widely diverse grades and kinds, as A. PyscHOMETRY, or nervous sensitiveness, wherein the subject does not see at all, but comes in magnetic contact with, first, the peculiar material emanations or sphere given off from every person or object in existence, and is analogous to the power whereby a dog finds his master in a crowd, or a hound hunts down a fugitive and pursues him unerringly, from having smelt a garment once
