Steiner's account in GA 109 of how the preserved etheric body of Zarathustra was woven into the child Moses, awakening the memory that wrote Genesis.
Moses and the Zarathustra Stream in Anthroposophy is Rudolf Steiner's account, given in the 1909 lecture cycle The Principle of Spiritual Economy (GA 109), of how the law-giver of Israel received the preserved etheric body of Zarathustra, the great initiate of ancient Persia. Steiner relates that Zarathustra instructed two intimate disciples; the second was reborn as Moses, and the etheric body of his teacher was woven into him. The infant's exposure in a basket of bulrushes on the water served, in this reading, as an initiation: cut off from the world, the inherited etheric forces could germinate before his own astral body and ego interfered. This awakened in Moses the power to read the Akasha Chronicle and to record the genesis of the earth in pictures. Anthroposophical biblical study, notably in The Christian Community, still reads the books of Moses through this inheritance.
Among the figures GA 109 follows, none carries a stranger gift than the law-giver. Moses and the Zarathustra Stream names the thread Steiner traces from the Persian initiate to Sinai: a disciple reborn, an etheric inheritance woven into a child, and a basket of bulrushes on the water that sealed the initiation. What looked like abandonment, Steiner says, was the careful awakening of another man's life-body within him.
In Steiner's Own Words
This disciple received in the following incarnation the etheric body of Zarathustra. The stories about this in religious documents are comprehensible only through these explanations. At his reincarnation, the student had to be animated in a very special way, that is the etheric body had to be strong before the astral body could be awakened. That could be achieved through the circumstances surrounding the birth of this reincarnated disciple, who was none other than Moses. The fact that he was placed into a box made of bulrushes that was allowed to float on the water and so on had the purpose of awakening completely the etheric body of the child. That enabled Moses to survey in his memory times long past, to pictorially record the genesis of the earth, and to read in the Akasha Chronicle.
What it Means Today
Steiner's Moses is not a borrower of doctrine but the bearer of a faculty. Hermes, who received Zarathustra's astral body, looked outward and perceived the mysteries spread through space; Moses, carrying his teacher's life-body, looked backward and read what unfolds in time. The Munich lecture of 7 March 1909 makes the difference exact: one disciple was given the perception of simultaneous events, the other the vision of successive ones. On that reading, the Genesis account is no compiled folklore. It is Akasha memory set down in pictures by the one man whose etheric inheritance reached to the beginnings of the earth.
That reading has had a working afterlife. Emil Bock, a co-founder of The Christian Community in Stuttgart in 1922, built his 1935 study Moses und sein Zeitalter on this premise, treating the Exodus narratives as the biography of an initiate rather than a literary patchwork. Readers who follow Bock's lead tend to handle Exodus 2 differently: the bulrush basket stops being a rescue anecdote and becomes the hinge of the whole biography, the moment a preserved Persian inheritance germinated inside a child of Israel. Whether one accepts the clairvoyant claim or brackets it, the interpretive habit it trains, asking what a figure carries before asking what he wrote, remains a distinct contribution to biblical reading.
