I believe what we call the end of the world is the end of the world of our knowing. There is no 'the world'. There is the world of every creature, which is not identical to the world of the knowing of any other creature, and that appearance ends with the end of the creature and its way of knowing. An individual doesn't have to help bring about the end of his or her world -- it will end with him or her. I agree that the world that each individual knows contributes to the worlds future individuals will know. At some point, I discovered that encounters that I have contribute to the world of my knowing. I believe I am alone and not alone, and that I am part of all worlds. Paying attention and reminding myself of that help me remember that. My world is the world of my knowing. It exists as a result of my way of knowing and wouldn't exist without me. I live in the world of my knowing but I don't live for it.
