neuter accusative singular
Analysis. ā- (toward) + kiñcañña (something, anything) + āyatana (sphere, realm). Literally 'the sphere of no-thing-ness', the meditative domain where consciousness rests on the absence of any particular object.
Etymology. From āyatana (sphere, dwelling-place) and the negated indefinite kiñcañña (anything). The prefix ā- marks direction and approach. The term is a canonical Pali coinage for this specific meditative attainment with no standard European cognates.
