The term ‘Heart Mind’ occupies a liminal and conceptually charged position across the depth-psychology corpus, naming the point at which cognition and feeling refuse separation. The passages gathered here span Orthodox hesychast practice, Taoist inner alchemy, Yogic psychology, Sufi mysticism, Jungian archetypal psychology, and Buddhist-inflected psychotherapy, yet they converge on a shared problematic: the Western inherited division between intellect and affect is either a pathological condition to be healed or a philosophical error to be corrected. Coniaris’s reading of St. Theophan frames the union of mind and heart as the telos of prayer; Welwood, following the Sanskrit chitta, observes that Buddhist usage collapses the distinction entirely, locating mind in the chest. Hillman, working through Corbin’s imaginal philosophy, argues that the heart is not a feeling organ opposed to thought but itself a mode of perception — ‘the thought of the heart.’ Sri Aurobindo distinguishes a purified heart, freed of reactive emotion, from the intellect, assigning each a proper domain in the integral ascent. The Taoist material, particularly Wilhelm and Liu I-ming, contrasts the ‘mind of Tao’ with the ‘human mentality,’ a distinction that maps closely onto the heart-mind duality. Collectively these voices reveal a sustained critique of cerebrocentric models of mind and an insistence that genuine knowing — whether called discernment, aisthesis, prajna, or imaginal perception — is cardiac in its locus.
