I have chosen for the subject of my lecture to-night one which I think is important—the Sixth Sub-Race. Both outside and inside the Theosophical Society a certain amount of good-humoured ridicule has been cast on the way in which Theosophists talk about Races, Sub-Races, Root-Races, Cycles, Rounds, and so on, some people condemning such talk as exceedingly unpractical. Really that is not so. When our great teacher H. P. Blavatsky traced for us _The Secret Doctrine_, that wonderful panorama of the past evolution of the Races on our globe, she was not only giving us the story of the past, but also presenting us with the key to the future. And I propose to-night to try to show you how it is possible for the Theosophist who has carefully studied the principles underlying past evolution, to apply these to the evolution of the future, and so learn how he may best co-operate with the divine plan which is slowly working itself out. The advantage of Theosophical teaching is that it gives us a definite scheme into which the evolution of mankind, stage by stage, fits without difficulty and without blunder. Now, if we think for a moment of what we call the larger and the smaller cycles, we can realise that the large scheme of the Races, the smaller scheme of the sub-races, and the evolution of man himself, all go along parallel lines. Understanding one, we can understand all. I will pause on the evolution of the Races, in order to remind you of the repetition, within the limit of each race, of the smaller sub-races. We need not go very far back. It will be enough to consider the Race that preceded our own, the great fourth Root Race, and our own. The fourth Root Race was the Atlantean. I only allude to it in order to remind you that from the midst of that race the Fifth Race, in its turn, arose. Now the choosing out of a new Race is the task of a particular Personage in the Occult Hierarchy, whose only name, so far as we know it, is that which has been borrowed from the Hindū, the Manu, the Man, or the Thinker, the ideal or typical man. The Manu forms in His own mind, after the master conception of the Planetary Logos, the plan of the man that is to be, which He will gradually realise along the lines of natural evolution. These laws of evolution are used by the Manu with scientific knowledge, and therefore with certainty. In the same way that a scientific breeder, dealing with the animal kingdom, can breed towards a desired type, so, on a higher plane, does the Manu of the Race mould by the same laws of evolution the physical form of the Race He desires to evolve. And always the type is formed in the matter of the higher planes before it is reproduced in the matter of the lower, the mental and emotional characteristics being first conceived, and then a physical body which will best express them. The Manu chooses the type according to the particular qualities which are to be evolved, which are marked out for Him by the basic plan of
