Now we are drawing to the practical side of our Lesson. The four principal points, you will please remember, are: (1) Intelligence. (2) Thought-Force. (3) Will-Power. (4) Self-Control. You might feel surprised at my retailing this "ancient history" instead of teaching you how to approach a man, make him your slave and command him to fall down at your feet and do your bidding. Perhaps you expected me to tell you how to sail through the air, pass through solid walls, materialize and dematerialize at will and like Appolonius of Tyana vanish in the flash of an eye from the court of Ionysius and appear elsewhere at a distance of 19,000 miles at the same moment. No, no. I will take it for granted that you are made of different stuff and _an earnest seeker after the truth_. If you strive to build yourself on the basis of the simple principles as laid down in this series of lessons you will in time grow into the Higher Self and at last become one with it. Moreover, your daily life will be the Occasion for the practical application of these principles, thus enabling you to pursue your way through life calmly, earnestly, independently and with the quiet dignity of a man "who knows what he is about". I cannot and would not speak of "get-rich-quick" methods of self-development because they are the veriest rot imaginable. Now then: (1) Intelligence and (2) Thought-Force are the natural results of an organised brain. Concentration is the key to such development. Concentration has been fully explained in Lesson No. 1. By the constant exercise of concentration, objectively and subjectively, in your daily life you will in a short time become conscious of growing Strength. The exercises I give you in this lesson on Self-Control, Will-Culture and Memory-Culture if gone through with perseverance will further develop Concentrative ability. In fact, this entire series of lessons will call for Effort and Concentration. "Rome was not built in a day"--nor can you achieve real greatness in a few months. No. All I can do is to indicate the line and the nature of the effort required of you and if clearly followed, Progress and Growth will commence from the first day. In connection with this, a little digression would be necessary. The Occultist says: Nature, unaided, fails. The purposiveness of Deity, manifesting in nature an evolution, is present in all individual centres but it has the way to full expression opened out to itself only when the more evolved centres of life consciously cooperate with it. Evolution is started and carried only by the creation of centres within the GREAT CONSCIOUSNESS and by preserving and enlarging or expanding these centres. So long as the race had not reached "SELF-CONSCIOUSNESS" (see Yoga Lessons) the sub-conscious forces of nature had entire control over evolutionary processes, but this stage was reached by the race according to the LAW OF AVERAGES in the seventeenth century and you are now
