There not unfrequently occur individuals so constituted that the spirit can perceive independently of the corporeal organs of sense, or can, perhaps, wholly or partially quit the body for a time and return to it again; the spirit communicates with spirit easier than with matter." We can now see how, after thousands of years have intervened between the age of the Gymnosophists* and our own highly civilized era, notwithstanding, or, perhaps, just because of such an enlightenment which pours its radiant light upon the psychological as well as upon the physical realms of Nature, over twenty millions of people today believe, under different form, in those same spiritual powers that were believed in by the Yogis and the Pythagoreans, nearly 3,000 years ago. -------- * The reality of the Yog-power was affirmed by many Greek and Roman writers, who call the Yogis Indian Gymnosophists--by Strabo, Lucan, Plutarch, Cicero (Tusculum), Pliny (vii. 2), &c. -------- Thus, while the Aryan mystic claimed for himself the power of solving all the problems of life and death, when he had once obtained the power of acting independently of his body, through the Atman, "self," or "soul;" and the old Greeks went in search of Atmu, the Hidden one, or the God-Soul of man, with the symbolical mirror of the Thesmophorian mysteries; so the spiritualists of today believe in the capacity of the spirits, or the souls of the disembodied persons, to communicate visibly and tangibly with those they loved on earth. And all these, Aryan Yogis, Greek philosophers, and modern spiritualists, affirm that possibility on the ground that the embodied soul and its never embodied spirit--the real self--are not separated from either the Universal Soul or other spirits by space, but merely by the differentiation of their qualities, as in the boundless expanse of the universe there can be no limitation. And that when this difference is once removed--according to the Greeks and Aryans by abstract contemplation, producing the temporary liberation of the imprisoned soul, and according to spiritualists, through mediumship--such a union between embodied and disembodied spirits becomes possible. Thus was it that Patanjali's Yogis, and, following in their steps, Plotinus, Porphyry and other Neo-Platonists, maintained that in their hours of ecstasy, they had been united to, or rather become as one with, God several times during the course of their lives. This idea, erroneous as it may seem in its application to the Universal Spirit, was, and is, claimed by too many great philosophers to be put aside as entirely chimerical. In the case of the Theodidaktoi, the only controvertible point, the dark spot on this philosophy of extreme mysticism, was its claim to include that which is simply ecstatic illumination, under the head of sensuous perception. In the case of the Yogis, who maintained their ability to see Iswara "face to
