 A further specificity worth noting is that the “elimination of opposite superimpositions” can bear on an object which is not the appearing object. For instance, a perception which has a patch of blue as its appearing object can eliminate the superimposition “non-blue” and thereby ascertain “blue,” but it can also eliminate the superimposition “presence of a patch of yellow” and thereby ascertain “absence of a patch of yellow” even though the absence of yellow does not appear to this perception. The first process is termed “direct realization” (dngos rtogs), the second “indirect realization” (shugs rtogs). A particular application of the “direct/indirect realization” model regards the realization or ascertainment that can be achieved via reflexive awareness (rang rig). Reflexive awareness allows the ascertainment of a range of features pertaining to the episode of awareness that is its apprehended object, and directly permits the indirect ascertainment of features pertaining to the object of that episode of awareness.
