In all this talk of impure perception and experiential perception there is something quite important to know, specially based in the Sakyapa view. When we say perception, everything is your perception, and all these perceptions are divided in into three, impure, experiential and pure, we are not indicating that these are our perceptions but there is something else truly existent as a perceiver or something beyond this perception. We are not saying that. That is all there is, impure perception, experiential perception and pure perception. What we see is all our perceptions and these perceptions change all the time. And they do not exist as a truly, independently, unchangingly. They don’t. We have explained this again and again. Like a friend, you look at your friend and when you are looking at your friend you are perceiving a phenomena which you refer as my best friend. For now anyway. With a little bit wrong information or something happening between you two over night changes. Overnight changes. Tomorrow you look at the same phenomena and then you are looking at someone that cannot be trusted, someone who has betrayed you, ugly, irritating. Neither that good guy and this bad guy, neither that yesterday’s good guy and the today’s bad guy they do not exist as an externally independently truly out there. That is the really the fundamental Sakyapa view. You have to register that.
