When we come to study it as one of the Lesser Mysteries, we shall feel that for its understanding some spiritual development is needed, some opening of the inner eyes. To grasp it requires that its spirit should be partly evolved in the life, and only those who know practically something of the meaning of self-surrender will be able to catch a glimpse of what is implied in the esoteric teaching on this doctrine, as the typical manifestation of the Law of Sacrifice. We can only understand it as applied to the Christ, when we see it as a special manifestation of the universal law, a reflection below of the Pattern above, showing us in a concrete human life what sacrifice means. The Law of Sacrifice underlies our system and all systems, and on it all universes are builded. It lies at the root of evolution, and alone makes it intelligible. In the doctrine of the Atonement it takes a concrete form in connection with men who have reached a certain stage in spiritual development, the stage that enables them to realise their oneness with humanity, and to become, in very deed and truth, Saviours of men. All the great religions of the world have declared that the universe begins by an act of sacrifice, and have incorporated the idea of sacrifice into their most solemn rites. In Hinduism, the dawn of manifestation is said to be by sacrifice,[216] mankind is emanated with sacrifice,[217] and it is Deity who sacrifices Himself;[218] the object of the sacrifice is manifestation; He cannot become manifest unless an act of sacrifice be performed, and inasmuch as nothing can be manifest until He manifests,[219] the act of sacrifice is called "the dawn" of creation. In the Zoroastrian religion it was taught that in the Existence that is boundless, unknowable, unnameable, sacrifice was performed and manifest Deity appeared; Ahura-mazdâo was born of an act of sacrifice.[220] In the Christian religion the same idea is indicated in the phrase: "the Lamb slain from the foundation of the world,"[221] slain at the origin of things. These words can but refer to the important truth that there can be no founding of a world until the Deity has made an act of sacrifice. This act is explained as limiting Himself in order to become manifest. "The Law of Sacrifice might perhaps more truly be called The Law of Manifestation, or the Law of Love and of Life, for throughout the universe, from the highest to the lowest, it is the cause of manifestation and life."[222]
