Luminosity

luminosity - 'od gsal - Literally 'free from the darkness of unknowing and endowed with the ability to cognize.' The two aspects are 'empty luminosity,' like a clear open sky, which is the cognizant quality of the nature of mind; and 'manifest luminosity,' such as five-colored lights, images, and so forth. Luminosity is the uncompounded nature present throughout all of samsara and nirvana [RY]
