Desire and Emptiness: Rethinking Fantasy Through the Diamond Sutra and Lacanian Psychoanalysis

The Diamond Sutra and Lacanian psychoanalytic theory, though grounded in distinct traditions, converge in their critique of the substantial “self,” revealing it as a fantasy produced by symbolic or conceptual structures. The Sutra dismantles attachment to “name-and-form,” asserting that realizing emptiness (śūnyatā) entails realizing non-self (anātman). Lacan, through the mirror stage, the Symbolic Order, and the Real, exposes the subject’s alienation within language, where desire continually circles around a constitutive lack. Both disclose that symbolic systems simultaneously generate and obscure reality. Practically, the Diamond Sutra prescribes the letting-go of all attachments—“letting the mind function without abiding anywhere”—while Lacan’s ethics of “traversing the fantasy” calls for confronting one’s fundamental lack and assuming responsibility for desire. By juxtaposing their approaches to the deconstruction of ego-fantasy, critique of symbolic mediation, and transcendence of illusion, this paper illuminates a shared insight into the interrelation of desire, language, and the real.
