This chapter traces the subtle body concept through the work of Carl Jung, who is introduced to the idea by G. R. S. Mead’s theosophical books. After tracing Jung’s early engagement with the Orient, the chapter moves to an analysis of the subtle body concept in his work, specifically in his engagements with Eastern traditions: Daoism, Kundalini Yoga, and Tibetan Bardo Yoga. After examining Jung’s use of the subtle body concept in his translation-commentaries on Eastern texts, the chapter turns to how Jung incorporates the concept into his own psychology of individuation based on the techniques of active imagination and dream analysis. The chapter turns to Jung’s seminars on Nietzsche, where he presents the subtle body concept with a unique dose of critical reflexivity and Kantian rigor. It ends with Jung’s late-life speculation about a future where, following the quantum revolution and spitting of the atom, humans evolve into subtle body–dwelling creatures who occupy a world of psychical substance.
