To the “sacrifice” of the person introverting, Jung devotes an entire chapter in his Psychology of the Unconscious, Chapt. IV. A brief résumé of it would show that by the sacrifice is meant the giving up of the mother, i.e., the disclaiming of all bonds and limitations that the soul has carried over from childhood into adulthood. The victory over the dragon is equivalent to the sacrificing of the regressive (incestuous) tendency. After we have sought the mother through introversion we must escape from her, enriched by the treasure which we have gotten. The sacrifice of a part of ourself (killing of the dragon, the father, etc.) is, as Jung points out, represented also in mythology by the shooting with sharp arrows at the symbol of the libido. The symbol of the libido is generally a sun symbol. Now it is particularly noteworthy that the VIII key of the alchemist Basilius Valentinus (see figure 3, p. 199) shows arrows being shot, which are aimed at the [Symbol: sun] (this libido symbol par excellence) that is aptly used as a “target.” Death is clearly enough accentuated and correlated with the sinking of the corns of wheat into the earth. [John XII, 24, 25, Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone; but if it die, it bringeth forth much fruit. He that loveth his life shall lose it; and he that hateth his life in this world shall keep it unto life eternal.] As this rises, so also will the dying mystic rise. The grave crosses have the form [Symbol: Fire] ([Symbol: Sulphur]); they show that the interred one is a certain sulphur, the impure sulphur, willfulness. The birds, from which we are to protect the grain, may in the end be the Siddhi; they are, in the introversion form of the religious work, what would otherwise be merely “diversions” or “dissipations.” The mystical death is the death of egoism (in Hindu terminology ahamkāra). Jacob Boehme writes in his book of the true atonement, I, 19: “... Although I am not worthy, [Jesus] take me yet in thy death and let me only in thy death die my death; still strike thou me in my acknowledged selfishness to the ground and kill my selfishness by thy death....” In the Mysterium Magnum, XXXVI, 74, 75: “... We exalt not the outspoken word of the wisdom of God, but only the animal will to selfishness and egoism which is departed from God, which honors itself as a false God of its own and may not believe or trust God (as the Antichrist who has placed himself in God’s stead); and we teach on the contrary that the man of the Antichrist’s image shall wholly die so that he may be born in Christ of a new life and will, which new will has power in the perfect word of nature with divine eyes to see all the miracles of God, both in nature and creature, in the perfect wisdom. For as dies the Antichrist in the soul, so rises Christ from the dead.”
