As this phenomenon becomes more frequent and more marked, ego and personality turn their attention more and more towards each other. The ego gains an increase of power to express himself in the lower worlds, is enriched by the added experiences which result, and so achieves a quickening of his evolution. The personality, in its turn, begins to find within itself a never-failing source of light, life, power and knowledge. From this point onwards, evolutionary progress is marked by a gradual fusion of the ego and the personality, which, as diagram 1 of Chapter VIII shows, indicates a definite stage in evolution. Until this stage is reached the ego must guard continually against the danger of a temporary or permanent loss of control, which might be caused by the dominance of certain habits of thought, feeling and action which have been acquired during the hundreds of lives in the past. He is always in conflict with the consciousness evolving through the matter of the mental, emotional and physical bodies, whose evolutionary tendency is down wards towards coarser rates of vibration and increasingly denser fields of self-expression. If, however, these difficulties are successfully overcome, the close relationship between the ego and the personality produces genius in the world of action. Side by side with this increase in the range of his powers in the lower worlds, an expansion of consciousness into the higher world above that of abstract thought begins. The power and radiance of the intuitional and spiritual level illumines him, and he begins to repeat in those worlds the processes through which he has passed in the lower. He builds vehicles through which he is able to gain contact with and express himself in those lofty levels. As a savage, his development is gained almost entirely by contact with the lower worlds; as a civilized man, he learns to acquire the added powers of egoic consciousness; as an initiate, he begins to withdraw from the lower, and to focus his consciousness in the higher worlds; as an Adept, his mastery over all is complete. He has learnt all that they can possibly teach him, and is free to leave them behind him forever, to dwell in realms of consciousness in which their limitations are unknown. No need hath such to live as ye name life; That which began in him when he began Is finished; he hath wrought the purpose through
