See “emptiness.”

A term used to express the absence of any intrinsic essence in all phenomena.

Emptiness (stong pa nyid), signlessness (mtshan ma med pa), and wishlessness (smon pa med pa) are known as the “three doors to deliverance” (triṇi­vimokṣa­mukhāni) or the “three concentrations” (trayaḥ samādhyaḥ) and as a set appear in both mainstream Buddhist sūtras and Mahāyāna sūtras. See Conze 1962, pp. 59–69; Lamotte 1944, pp. 1213–15; and Deleanu 2000, pp. 74–78.
