Will is the development of the wish. When one says, "It was the divine will" it means that it was a command, a wish that developed into action. When the wish becomes action it becomes will, it becomes a command. One may think it is only one's wish, but it is a wish as long as it is still. It is there, it has not sprung up, it is inactive, just like a seed in the ground: it is wish. But the moment the seed is coming out of the ground as a seedling and is in the process of becoming a plant, then it is a will. Therefore these two different names, wish and will, are names of one and the same thing: in its undeveloped state and in its process of development.
