to the sense (_pûrvad@r@s@tâparad@r@s@tañcârthamekîkurvadvijñânamasannihitavi@sayam pûrvad@r@s@tasyâsannihitatvât_). In all illusory perceptions it is the sense which is affected either by extraneous or by inherent physiological causes. If the senses are not perverted they are bound to present the object correctly. Perception thus means the correct presentation through the senses of an object in its own uniqueness as containing only those features which are its and its alone (_svalak@sa@nam_). The validity of knowledge consists in the sameness that it has with the objects presented by it (_arthena saha yatsârûpyam sâd@rs'yamasya jñânasya tatpramâ@namiha_). But the objection here is that if our percept is only similar to the external object then this similarity is a thing which is different from the presentation, and thus perception becomes invalid. But the similarity is not different from the percept which appears as being similar to the object. It is by virtue of their sameness that we refer to the object by the percept (_taditi sârûpyam tasya vas'ât_) and our perception of the object becomes possible. It is because we have an awareness of blueness that we speak of having perceived a blue object. The relation, however, between the notion of similarity of the perception with the blue object and the indefinite awareness of blue in perception is not one of causation but of a determinant and a determinate (_vyavasthâpyavyavasthâpakabhâvena_). Thus it is the same cognition which in one form stands as signifying the similarity with the object of perception and is in another indefinite form the awareness as the percept (_tata ekasya vastuna@h kiñcidrûpam pramâ@nam kiñcitpramâ@naphalam na virudhyate_). It is on account of this similarity with the object that a cognition can be a determinant of the definite awareness (_vyavasthâpanaheturhi sârûpyam_), so that by the determinate we know the determinant and thus by the similarity of the sense-datum with the object {_pramâ@na_) we come to think that our awareness has this particular form as "blue" (_pramâ@naphala_). If this sameness between the knowledge and its object was not felt we could not have spoken of the object from the awareness (_sârûpyamanubhûtam vyavasthâpanahetu@h_). The object generates an awareness similar to itself, and it is this correspondence that can lead us to the realization of the object so presented by right knowledge [Footnote ref l]. ____________________________________________________________________
