The Dzogchen teachings are very precise in talking about rigpa and categorizing it with many subtle distinctions. So a distinction is made between the ground of being and the appearances of that ground, and effulgent rigpa (Tib. རྩལ་གྱི་རིག་པ་ , Wyl. rtsal gyi rig pa) is rigpa that is present in the appearances arising from the ground.
It’s an aspect of rigpa which is to be identified and experienced only when coarse levels of mind and conceptual thoughts are active. At that point the experience of the fundamental innate mind of clear light has ‘ceased’―‘ceased’ in the sense that it is no longer a direct object of your experience. However, there is still a definite quality of clarity and awareness that permeates the coarser states of consciousness. This type of clear light experienced as a quality that permeates these states is the effulgent rigpa.
