This means that as every planet is a world, so every mind is a world; it is a living world. The question is, if we make our world and mold our life, why should we have unhappiness, why have troubles in life, why have failures in life? The answer is that it is neither the fault of the Creator nor of the world; it is the fault of our ignorance; it is our lack of knowledge. Buddha pictures this lack of knowledge in this way: it is as if you are clinging to the branch of a tree in the thick darkness of night so that you cannot see what is beneath you, whether it is land or sea; so you are all the time afraid of falling. You keep on clinging to the tree and suffering with the fear of how long it will be before you have to let go, thinking, "How long can I cling to this branch?" Yet under your feet there is nothing to be seen. Such is life until light comes. Then it is like the coming of the sun. When the sun rises you find there is no water, and hardly any space; for the ground is just beneath your feet.
