upādi: lit. 'something which one grasps, to which one clings, i.e. the 5 groups of existence (khandha, q.v.). In the Suttas , the word is mostly used in such expressions as "One of the 2 fruits may be expected: either perfect wisdom or, if the groups are still remaining (sati upādi-sese, 'if there is a remainder of groups ), Anāgāmīship" (D. 22). Further (A. IV. 118): "Here the Perfect One has passed into the Nibbāna-element in which no more groups are remaining (anupādi-sesa)." Cf. Nibbāna.
