neuter singular accusative; the eighth āruppajjhāna (formless absorption) in Buddhist meditative path
Analysis. viññāṇa (consciousness) + añca (abbreviated form of ca, 'and') + āyatana (base, sphere, realm) — 'the base where consciousness [alone is perceived]'; the eighth of the four formless absorptions (āruppajjhāna), where meditators perceive only the subtlest consciousness without even the perception of nothingness.
Etymology. viññāṇa from vi- + √jñā (knowing apart; cognate with Latin gnoscere, English know via Germanic cognate); āyatana from √i 'to go' (that which goes forth, a gateway or base). This is a technical doctrinal term for the highest non-theistic meditative state before the cessation of perception and feeling.
