Is There Any Knower Behind Thoughts?

In the psychology of dalism, there is no difference between you as observer and whatever it is that you observe. There isn't a knower facing the known. It would be more like saying that if there is any knower at all, it contains the knower. Your head is in your mind because your mind understood from the standpoint of vision is space. The Chinese use this word, who? which means sky, space and sometimes emptiness. This is actually a Buddhist saying from the Tridaya sutra.
