 The adoption of the criteria of “eliminating superimpositions” in the definition of reliable cognition does not affect inference. According to Chapa, however, “elimination of superimpositions” is not limited to conceptual cognition in general. It has a broader scope than the kind of conceptual operation that follows an intentional determination (zhen pa). Perception, although it does not perform any intentional determination, is indeed capable of eliminating superimpositions. It does so via a causal process: perception gives rise, at the next moment, to another non-conceptual mental episode in which the potential of the wrong superimposition to arise has been neutralized, thus preventing its subsequent arising. By the third moment, there are no more superimpositions. Insofar as it, by this means, eliminates opposite superimpositions, perception is reliable and can be held to ascertain (nges pa) its object, without involving any conceptual element. Whether a conceptual determination occurs subsequently or not is irrelevant to the reliability of the preceding perceptual awareness.
