There cannot be a better example to demonstrate the idea behind the symbolical tree than this story. For this tree is this whole universe, the miniature of which is one's own self, and there is nothing that you ask that this universe will not answer, for it is the nature of the universe to answer your soul's call. Only, if you ask for the pears, there are pears, if one asked for a cactus, there is a cactus, if you ask for the rose there will be the rose and its thorns together. And it is the lack of knowledge of this great secret hidden in the heart of the universe which is the only tragedy of life. When a person seeks for something in the universe and he cannot find it, it is not true that it is not there, the fact is that he does not see it.
