I never had the slightest idea of this internal light, till, in the way of experiment, I inhaled the sulphuric ether; but I am now very well able to conceive it: for, after first feeling an agreeable warmth pervading my limbs, my next sensation was to find myself, I can not say in this heavenly light, for the light was in _me_—I was pervaded by it: it was not perceived by my eyes, which were closed, but perceived internally, I can not tell how. Of what nature this heavenly light was—and I can not forbear calling it _heavenly_, for it was like nothing on earth—I know not, nor how far it may be related to those luminous emanations occasionally seen around ecstatics, saints, martyrs, and dying persons; or to the flames seen by somnambules issuing from various objects, or to those observed by Von Reichenbach’s patients proceeding from the ends of the fingers, &c. But at all events, since the process which maintains life is of the nature of combustion, we have no reason to be amazed at the presence of luminous emanations; and as we are the subjects of various electrical phenomena, nobody is surprised when, on combing their hair or pulling off their silk-stockings, they hear a crackling noise, or even see sparks. Light, in short, is a phenomenon which seems connected with all forms of life; and I need not here refer to that emitted by glow-worms, fire-flies, and those marine animals which illuminate the sea. The eyes also of many animals shine with a light which is not merely a reflected one—as has been ascertained by Rengger, a German naturalist, who found himself able to distinguish objects in the most profound darkness, by the flaming eyes of a South American monkey. “The seeing of a clear-seer,” says Dr. Passavent, “may be called a _solar_ seeing, for he lights and inter-penetrates his object with his _own_ organic light, viz., his nervous ether, which becomes the organ of the spirit;” and under certain circumstances this organic light becomes visible, as in those above alluded to. Persons recovering from deep swoons and trances, frequently describe themselves as having been in this region of light—this light of the spirit, if I may so call it—this palace of light, in which it dwells, which will hereafter be its proper light; for the physical or solar light, which serves us while in the flesh, will be no longer needed, when out of it, nor probably be perceived by the spirit, which will then, I repeat, be a light to itself: and as this organic light—this germ of our future spiritual body—occasionally becomes partially visible now, there can not, I think, be any great difficulty in conceiving that it may, under given circumstances, be so hereafter.
