The donkeys are the various doctrines that each of us embraces. Your donkey might be a Zen donkey, mine might be a Tao donkey. There are Christian, Islamic, Jewish, and even Agnostic donkeys. All lead to the same place. We should put aside both the donkeys and our interim experiences once we arrive at the summit.
All religions have different names for the ways of getting to the holy summit.
Once we reach the summit, we no longer need names, and we can experience all things directly. I do not see the road ahead of me. I cannot know for certain where it will end. Nor do I really know myself, and the fact that I think that I am following your will does not mean that I am actually doing so. But I believe that the desire to please you does in fact please you.
