How did Jung reinterpret karma in psychological terms?

Jung's engagement with karma is one of the more careful moments in his dialogue with Eastern thought — careful because he refused both the metaphysical literalism of the doctrine and the dismissive reduction that would have made it merely superstition. What he found in karma was a structural parallel to something he had already discovered empirically: that the psyche carries inherited patterns that no individual biography can explain.

The move is stated plainly in his commentary on The Tibetan Book of the Dead. Jung writes that karma implies

a sort of psychic theory of heredity based on the hypothesis of reincarnation, which in the last resort is an hypothesis of the supra-temporality of the soul.

He then brackets the reincarnation hypothesis entirely — not because he thought it false, but because he held that psychology cannot adjudicate metaphysical claims — and asks what remains when you strip karma of its cosmological scaffolding. What remains is the inheritance of psychic characteristics: predispositions to disease, traits of character, special gifts, and, at the deepest level, the universal dispositions of the mind that he called archetypes. These are not the karma of a particular individual's past lives; they are the accumulated inheritance of the species, the "omnipresent, but differentiated, psychic structure which is inherited and which necessarily gives a certain form and direction to all experience" (Evans-Wentz edition, Jung's commentary). The archetypes, on this reading, are karma depersonalized and collectivized — not what you did in a previous life, but what humanity has been doing for millennia, crystallized into the organs of the pre-rational psyche.

Clarke's study of Jung's Eastern dialogues captures the interpretive logic precisely: Jung treated karma as he treated every Eastern metaphysical concept — phenomenologically, asking not whether the doctrine is cosmologically true but what psychic reality it points toward. The concept of karma gave him confidence, he acknowledged, in his belief that the individual mind must be understood in terms far wider than a single lifetime. It interacted constantly with his developing notion of the archetype, functioning as a kind of cross-cultural corroboration that the psyche is shaped by factors historically deeper than personal experience.

There is, however, a critical asymmetry Jung was careful to preserve. Karma in its traditional form implies moral retribution — the suffering of this life as payment for the sins of a previous one. Jung found this framework philosophically untenable. As he wrote to a correspondent in 1938, the East sought to eliminate suffering by "casting it off," but the only way to meet suffering was to endure it — a position he aligned, perhaps surprisingly, with the Christian model of bearing the cross rather than the Indian model of transcending the cycle (Letters I: 236). The karmic logic of escape — if I accumulate enough merit, or achieve enough detachment, I will not suffer — is precisely the pneumatic current running through Indian soteriology, and Jung's resistance to it is consistent: complete redemption from the sufferings of this world "is and must remain an illusion" (CW 16.400).

What Jung preserved from karma, then, is its structural insight — that the psyche is not a blank slate, that we arrive already shaped by something older than ourselves — while refusing its moral economy of reward and punishment and its promise of liberation from the cycle. The collective unconscious is karma without the escape clause: inherited depth without the guarantee of transcendence.
