[1440] An exalted phenomenon (mahaggato dhammo) is a condition for a measureless phenomenon (appamāṇa dhamma) by immediacy condition (anantara-paccaya). The sphere of neither-perception-nor-non-perception (nevasaññānāsaññāyatana) is a condition, by immediacy condition, for the fruition attainment (phala-samāpatti) of one emerging from cessation (nirodha).
