Nirvana occupies a pivotal and contested position within the depth-psychology corpus, functioning simultaneously as a soteriological terminus, a psychological state, and a metaphysical absolute that resists any single disciplinary framing. The corpus reveals three broad orientations. First, the classical Buddhist-scholastic approach, represented by Suzuki, Evans-Wentz, and Coleman, treats nirvana as the permanent cessation of suffering and the extinction of conditioned existence — yet insists, against crude negativism, on an affirmative, experiential content: enlightenment, bliss, and liberation from ignorance. Second, a comparative-perennialist strand, evident in Armstrong, Campbell, and Watts, identifies nirvana with the Void (sunyata), with Brahman-Atman realization, and with the Absolute, drawing explicit parallels to Neoplatonic and mystical traditions elsewhere in the library. Third, a psychological-experiential register, prominent in Easwaran, Aurobindo, and Spiegelman, translates nirvana into the annihilation of the ego-boundary, the discovery of the Self beyond separateness, and a state accessible through meditation disciplines. The unresolved tension that animates these readings is whether nirvana names a positive plenitude, a negative extinction, or a condition simply beyond the categories through which either could be predicated — a question the Buddha himself, as several authors note, deliberately refused to adjudicate.
