This, then, as we came to learn, and to recognise as having learned it in our own long-past lives, is the doctrine which Jesus came to teach and to demonstrate in His own person. Matter is spirit, being spiritual substance, projected by force of the divine Will into conditions and limitations, and made exteriorly cognisable. And being spirit it can revert to the condition of spirit. In virtue of the divinity of his constituent principles, man has within himself the seed of his own regeneration, and the power to effectuate it. He has in him, this is to say, the potentiality of divinity realisable at will. And the secret and method of the achievement, which is no other than the secret and method of Christ, is inward purification and unfoldment, the unfoldment of the capacities, mental, moral, and spiritual, of his nature, of which inward purification is the first and essential condition. Thus is the Finding of Christ the realisation of the Ideal, and Christ is for every man the summit of his own evolution. Stated in terms of modern science, but correcting its aberrations, the doctrine of Christ is in this wise. Evolution is the manifestation of inherency. Owing to the divinity of the constituent principles of existence, its Force and its Substance, both of which are God, the inherency of existence is divine. Wherefore, as the manifestation of a divine inherency, evolution is accomplished only by the attainment of divinity; and the cause of evolution is the tendency of substance to revert from its secondary and "created" condition of matter, to its original and divine condition of pure spirit. Wherefore evolution is definable as the process of the individuation of Deity in and through Humanity. Such is the genesis of the Christ in man. And he is called _a_ Christ who, having accomplished this process in himself, returns into the earth-life when he has no need to do so for his own sake, out of pure love to redeem, by showing to others their own equal divine potentialities and the method of the realisation thereof. This method consists in love, love of perfection, which is God, for its own sake, and love for others. The process is entirely interior to the individual. It consists in the sacrifice of the lower nature to the higher in himself, and of himself for others in love. That which directly saves the man is not the love of another for the man, but the love which he has in himself. All that can be done by another is to kindle this love in him.
