We can notice, looking back, that there are four great ages through which the world passes in its long evolutionary history, ages that are often referred to in what are called the mythologies of the past, ages which are characterised very differently the one from the other, and in which the whole cycle of the world’s story is divided. It may be noticed that at the beginning of each of those huge cycles a very great figure appears, as though, when the world was entering on a new phase of life, it were necessary that a special benediction should descend upon it, a special light should shine out. When we ask who are the great Ones who mark these longest periods in human history, we are told that They are Beings belonging to past worlds, belonging to other planets than our own, planets and worlds older in the scale of manifestation; that They have passed through all the struggles of an evolving life, that They have formed part of a humanity that long since has passed away and been numbered in the records of the universe, too far off to touch a world like ours; that, reaching through human to superhuman growth, They have finally joined their consciousness with the consciousness of the Logos Himself, expanding to His consciousness, uniting with His nature, and yet never losing that centre which is the result of Their long evolution up the human and the superhuman ladder. Holding that centre in all the life of God, it is possible for Them to draw around Themselves again a circumference which shall enable Them to become manifest in any world, in any race. Where a centre is, a circumference can ever be drawn; and around such a centre in Deity itself, of the Son made one with the Father, from such a centre a new circumference of a human life may be drawn, and such a Being, mighty in His Deity and yet veiled in humanity, may appear to enlighten and to bless the world. Among the Hindū people, whose teachers have carried them far along occult lines, whose sacred scriptures are full of occult indications, a special name is given to these pre-eminent manifestations. They call them by a Sanskrit word which means those who descend. The name avatāra may be familiar to you, perhaps. But it is the significance of the name on which for a moment I pause. They have climbed up to unity with the God head: They descend to humanity in order to preserve and help. Such are the mightiest figures that appear in any world, on any globe, through the long course of its evolution. Egypt signified that mystery under a special name: they called it the birth of Horus. Christianity has symbolised it under another name—Divine Incarnation; and the Christian will tell you—accurate in the spiritual fact, although at times confused in the definition of the life—that the Second Person of the Trinity descends upon earth, and he regards the Christ of Judea as being such a manifestation of the Most High. The main fact that such a revelation may come to man is a fundamental spiritual truth.
