The teaching from GA 109 that the etheric and astral bodies of great individualities do not dissolve at death but are kept in the spiritual world for later use.
The Preservation of the Sheaths in Anthroposophy is the teaching that the etheric and astral bodies of great individualities do not dissolve after death, as they ordinarily would, but are held intact in the spiritual world for the future service of humanity. Rudolf Steiner presented it in The Principle of Spiritual Economy (GA 109), opening the cycle at Heidelberg on 21 January 1909. Normally the etheric body disperses as a second corpse and the astral body dissolves after kamaloca; when a sheath has been worked through by an initiate, however, it becomes too valuable to be lost and is kept like a mold that can be imprinted on people of later ages. Steiner relates that the Manu preserved the seven etheric bodies of the greatest Atlantean oracle initiates for the seven Rishis of ancient India. For modern readers the teaching reframes how spiritual capacity passes from one generation to another.
Most etheric and astral bodies return to their elements once a life has ended. The Preservation of the Sheaths names the exception: where decades of inner work have refined these vehicles, the spiritual world keeps them whole. Steiner traced the practice back to Atlantis, where the Manu guarded seven such etheric bodies, and forward to figures as recent as Galileo, whose life-body served a later scientist.
In Steiner's Own Words
The greatest of these sages in the oracles had worked so much into their etheric bodies that the latter had become too valuable simply to be dissipated into the general etheric world. Therefore, the seven best etheric bodies belonging to the seven greatest initiates were preserved until the Manu had developed the seven most outstanding people from his group in such a way that they were suited to absorb the preserved etheric bodies. Only the etheric body of the Great Initiate of the Christ Oracle was, in a certain sense, treated differently from the others. And so the seven sages, or Rishis, who had received the seven etheric bodies of the greatest initiates, went to India, where they became the founders and great teachers of Indian culture.
What it Means Today
Historians of science keep meeting continuity that documents cannot explain. Nicholas of Cusa set down the essentials of the heliocentric picture a century before Copernicus published his system; Mikhail Lomonosov came out of a poor Russian village to become the founder of Russian grammar and classical literature, the polymath whose name Moscow State University, founded in 1755, still carries. Steiner read both riddles through the preserved bodies. According to GA 109, the astral body of Cusa was transferred to Copernicus, and the etheric body of Galileo, "the carrier of his memory and talent," was given over to Lomonosov, though neither receiver was the reincarnation of his predecessor. Whoever weighs this account finds that it changes the question a biography asks: talent arriving without lineage stops looking like a genetic accident and begins to look like an inheritance of a different order.
The teaching also carries Steiner's own caution, and this is its practical edge. A preserved sheath can be woven into a person who shares nothing with the donor's ego, so someone might bear Galileo's life-body without ever having been Galileo. Steiner warned that occultists who mistake a carried sheath for their own former incarnation set their soul's development on a wrong course. Anyone who meets a modern past-life claim can apply the same sober test he gave his Heidelberg listeners in January 1909: ask first whether what returned was the individuality itself, or only the finished garment it once wore.
