'Innate enlightenment' or 'original enlightenment.' The possession by sentient beings of enlightenment as their basic nature， which means that enlightenment is not something to be obtained externally， or as a distant goal， but exists in full reality here in the present moment， and therefore sentient beings need only to awaken to it. This is a concept expressed commonly in scriptural works of East Asian provenance， such as the Awakening of Faith 起信论 and the Sutra of Perfect Enlightenment 圆觉经. It is due to this East Asian origin that there are no direct Indic terms indicated as sources for the concept， which in turn offers support to the argument for the East Asian provenance of such texts. It is in the Awakening of Faith in particular where the background of the doctrine is developed in detail， where it is explained in contrast to "initial （actualized） enlightenment" 始觉， as transcending the dualistic opposition of enlightenment 觉 vs. non-enlightenment 不觉.
