Lit. “non-loss of mindfulness.” Name of a meditative stabilization.

One of the three qualities of mindfulness (dran pa; smṛti) including familiarization (’dris pa’i dngos po; samstute vastuni) and nondistraction (mi g.yeng ba; avikṣipta). See, for example, Jaini 1992 (pp. 47–59) on asaṃpramoṣa in Abhidharma literature. The “absorption of nonforgetfullness” (asaṃpramoṣo nāma samādhiḥ) is listed in the Mahāvyutpatti §526.
