The allegorical expression of the Hindû mystics who speak of the “Eye of Shiva,” the Tri‐lochana, or “three‐eyed,” thus receives its justification and _raison d’être_: the transference of the Pineal Gland (once that Third Eye) to the forehead, being an exoteric licence. This throws also a light on the mystery—incomprehensible to some—of the connection between _abnormal_, or spiritual Seership, and the physiological purity of the Seer. The question is often asked: Why should celibacy and chastity be a _sine quâ non_ condition of regular Chelâship, or the development of psychic and occult powers? The answer is contained in the Commentary. When we learn that the Third Eye was once a physiological organ, and that later on, owing to the gradual disappearance of spirituality and increase of materiality, the spiritual nature being extinguished by the physical, it became an atrophied organ, as little understood now by Physiologists as is the spleen—when we learn this, the connection becomes clear. During human life the greatest impediment in the way of spiritual development, and especially to the acquirement of Yoga powers, is the activity of our physiological senses. Sexual action also being closely connected, by interaction, with the spinal cord and the grey matter of the brain, it is useless to give any longer explanation. Of course, the normal and abnormal state of the brain, and the degree of active work in the Medulla Oblongata, reacts powerfully on the Pineal Gland, for, owing to the number of “centres” in that region, which controls by far the greatest number of the physiological actions of the animal economy, and also owing to the close and intimate neighbourhood of the two, a very powerful “inductive” action must be exerted by the Medulla on the Pineal Gland. All this is quite plain to the Occultist, but is very vague in the sight of the general reader. The latter must then be shown the possibility of a three‐eyed man in Nature, in those periods when his formation was yet in a comparatively chaotic state. Such a possibility may be inferred from anatomical and zoological knowledge, first of all, and then it may rest on the assumptions of Materialistic Science itself.
