Luminous mind

 (Skt: prabhāsvara-citta or ābhāsvara-citta, : pabhassara citta; T. ’od gsal gyi sems; C. guangmingxin; J. kōmyōshin; K. kwangmyŏngsim) is a Buddhist term which appears in a sutta of the Pali as well as numerous Mahayana texts and Buddhist tantras. It is variously translated as "brightly shining mind", or "mind of clear light" while the related term luminosity (Skt. prabhāsvaratā; Tib.’od gsal ba; Ch. guāng míng; Jpn. kōmyō; Kor. kwangmyōng) is also translated as "clear light" in Tibetan Buddhist contexts or, "purity" in East Asian contexts.

 * People who practice mental concentration may inhibit the True Mind within themselves by being dependent on sensory perceptions, coarse states of mind, and restricted breathing. Before achieving mental purity, [such people may undertake] the constant practices of concentrating the mind and viewing the mind. Although they do so during all their activities, [such people] cannot achieve [mental] clarity and purity, nor illumine that mind which is the sources of all dharmas.
