I must, however, positively and firmly state that while these cases and illustrations, these quotations and citations, are purely Western, the principles they illustrate and prove are among the oldest known to Hindu occult science and philosophy. In fact, having been accepted as proved truth in India, for centuries past, there is very little demand for further proof thereof on the part of the Hindus. In the Western world, however, these things are comparatively new, and must be proved and attested accordingly. So, as I have said, I have cut the cloth of my instruction to conform with the pattern favored for the Western garment of knowledge. So far as the illustrations and cases, the quotations and citations are concerned--these are purely Western and familiar to the student. But, when it comes to the principles themselves, this is another matter--I must be pardoned for stating that these are the outgrowth of Hindu thought and investigation, and that he who would discover their roots must dig around the tree of the Wisdom of the East, which has stood the storms and winds of thousands of years. But the branches of this mighty tree are wide-spreading, and there is room for many Western students to rest in its shade and shelter. In these lessons I have referred occasionally to my two little books, entitled "The Astral World," and "The Human Aura," respectively. To those who are interested in these subjects, I recommend these little books; they are sold at a nominal price, and contain much that will be helpful to the student of Hindu Occult Science. They are not required, however, to complete the understanding of the subjects treated upon in these lessons, and are mentioned and recommended merely as supplementary reading for the student who wishes to take little "side excursions" away from the main trip covered in these lessons. I trust that my students will find the pleasure and satisfaction in studying these lessons that I have in writing them. SWAMI PANCHADASI. LESSON I. THE ASTRAL SENSES. The student of occultism usually is quite familiar with the crass individual who assumes the cheap skeptical attitude toward occult matters, which attitude he expresses in his would-be "smart" remark that he "believes only in what his senses perceive." He seems to think that his cheap wit has finally disposed of the matter, the implication being that the occultist is a credulous, "easy" person who believes in the existence of things contrary to the evidence of the senses. While the opinion or views of persons of this class are, of course, beneath the serious concern of any true student of occultism, nevertheless the mental attitude of such persons are worthy of our passing consideration, inasmuch as it serves to give us an object lesson regarding the childlike attitude of the average so-called "practical" persons regarding the matter of the evidence of the senses.
