Man has further "a spiritual body." This is made up of three separable portions, each portion belonging to one of, and separating off, the three Persons in the Trinity of the human Spirit. S. Paul speaks of being "caught up to the third heaven," and of there hearing "unspeakable words which it is not lawful for a man to utter."[243] These different regions of the invisible supernal worlds are known to Initiates, and they are well aware that those who pass beyond the first heaven need the truly spiritual body as their vehicle, and that according to the development of its three divisions is the heaven into which they can penetrate. The lowest of these three divisions is usually called the Causal Body, for a reason that will be only fully assimilable by those who have studied the teaching of Reincarnation--taught in the Early Church--and who understand that human evolution needs very many successive lives on earth, ere the germinal soul of the savage can become the perfected soul of the Christ, and then, becoming perfect as the Father in Heaven,[244] can realise the union of the Son with the Father.[245] It is a body that lasts from life to life, and in it all memory of the past is stored. From it come forth the causes that build up the lower bodies. It is the receptacle of human experience, the treasure-house in which all we gather in our lives is stored up, the seat of Conscience, the wielder of the Will. The second of the three divisions of the spiritual body is spoken of by S. Paul in the significant words: "We have a building of God, an house not made with hands, eternal in the heavens."[246] That is the Bliss Body, the glorified body of the Christ, "the Resurrection Body." It is not a body which is "made with hands," by the working of consciousness in the the lower vehicles; it is not formed by experience, not builded out of the materials gathered by man in his long pilgrimage. It is a body which belongs to the Christ-life, the life of Initiation; to the divine unfoldment in man; it is builded of God, by the activity of the Spirit, and grows during the whole life or lives of the Initiate, only reaching its perfection at "the Resurrection." The third division of the spiritual body is the fine film of subtle matter that separates off the individual Spirit as a Being, and yet permits the interpenetration of all by all, and is thus the expression of the fundamental unity. In the day when the Son Himself shall "be subject unto Him that put all things under Him, that God may be all in all,"[247] this film will be transcended, but for us it remains the highest division of the spiritual body, in which we ascend to the Father, and are united with Him.
