What is the medium through which it attacks?

It is a lie that some appearance causes trouble, no appearance can actually touch us. It does not really touch what we are. And I have been asking some of you recently that how is it that something outside appearing there can actually touch the reality of who we are. What is the medium through which it can attack the me, the eye? Is there some way in which that which appears can attack the reality of who we are? Can you see this now? Can we check at least outside the body and see that the dance of another or the dance of the world in front of us? It cannot really hurt what really truly is. How can something appearing there, moving there, hurt the reality of what we are?
