YOGA FOR YAHOOS SECOND LECTURE. YAMA. Do what thou wilt shall be the whole of the Law. Stars and placental amniotes! And ye inhabitants of the ten thousand worlds! The conclusion of our researches last week was that the ultimate Yoga which gives emancipation, which destroys the sense of separateness which is the root of Desire, is to be made by the concentration of every element of one's being, and annihilating it by intimate combustion with the universe itself. I might here note, in parenthesis, that one of the difficulties of doing this is that all the elements of the Yogi increase in every way exactly as he progresses, and by reason of that progress. However, it is no use crossing our bridges until we come to them, and we shall find that by laying down serious scientific principles based on universal experience they will serve us faithfully through every stage of the journey. 2. When I first undertook the investigation of Yoga, I was fortunately equipped with a very sound training in the fundamental principles of modern science. I saw immediately that if we were to put any common sense into the business (science is nothing but instructed common sense), the first thing to do was to make a comparative study of the different systems of mysticism. It was immediately apparent that the results all over the world were identical. They were masked by sectarian theories. The methods all over the world were identical; this was masked by religious prejudice and local custom. But in their quiddity—identical! This simple principle proved quite sufficient to disentangle the subject from the extraordinary complexities which have confused its expression. 3. When it came to the point of preparing a simple analysis of the matter, the question arose: what terms shall we use? The mysticisms of Europe are hopelessly muddled; the theories have entirely overlaid the methods. The Chinese system is perhaps the most sublime and the most simple; but, unless one is born a Chinese, the symbols are of really unclimbable difficulty. The Buddhist system is in some ways the most complete, but it is also the most recondite. The words are excessive in length and difficult to commit to memory; and generally speaking, one cannot see the wood for the trees. But from the Indian system, overloaded though it is by accretions of every kind, it is comparatively easy to extract a method which is free from unnecessary and undesirable implications, and to make an interpretation of it intelligible to, and acceptable by, European minds. It is this system, and this interpretation of it, which I propose to put before you. 4. The great classic of Sanskrit literature is the Aphorisms of Patanjali. He is at least mercifully brief, and not more than ninety or ninety-five
