asaṅkhārika-citta: an Abhidhamma term signifying a 'state of consciousness arisen spontaneously', i. e. without previous deliberation, preparation, or prompting by others; hence: 'unprepared, unprompted'. This term and its counterpart (sasaṅkhārikacitta, q.v.), probably go back to a similar distinction made in the Suttas (A. IV, 171; "Path" 184). See Tab. I; examples in Vis.M. XIV, 84f.
