Zen master Seung-Sahn talked about “only don’t know mind.” This whole area is very powerful if it comes out of your awareness. Knowing and not knowing is something the egoistic mind creates. It is necessary to go into not knowing first and not to panic into your ego with, “I know.” The grasping mind will not allow an open dimension. In the area of consciousness that is without form, your knowledge will begin to crack apart. Depending on your attachment to intellect, you may eventually have to come to this “I don’t know” bardo.
