一念

A (sa) kṣaṇa, or thought; a concentration of mind; a moment; the time of a thought, of which there are varying measurements from 60 (sa) kṣaṇa upwards; the <Fan-yi-ming-yi> makes it one (sa) kṣaṇa. A reading. A repetition (especially of Amitābha's name). The Pure-land sect identify the thought of Buddha with Amitābha's vow, hence it is an assurance of salvation.
