(Tib., 'od-gsal; Skt., prabhāsvara).
Often translated as ‘radiant light’ or ‘clear light’, this term refers to the intrinsic purity of the mind (prakṛti-prabhāsvara-citta) in contrast to the illusory, adventitious defilements which seem to obscure it. Though the concept was known from the earliest times in Buddhism.it gained prominence particularly in the Tathāgata-garbha teachings and later tantric derivatives. According to this view, the mind has two complementary aspects—emptiness and radiance—which both need to be realized and united for enlightenment (bodhi). Practices associated with this concept also form part of the Six Yogas of Nāropa.
