I do not know how many of you have read the Bible; it is not very entertaining to read it, and besides, it is very long, but still, in the Bible there is a story I have always liked very much. There were two brothers, if I am not mistaken, Esau and and Jacob. Well, Esau was very hungry, that is the story, is it not so? I believe he was a hunter or something; anyway, the story goes like this. He came back home very hungry, and told Jacob he was very hungry, and he was so hungry that he said to him: "Listen, if you give me your mess of pottage" (Jacob had prepared some stew), "if you give me your mess of pottage I will give you my birthright." You know, one can understand the story quite superficially, but it has a very profound meaning. The birthright is the right of being the son of God. And so he was quite ready to give up his Divine right because he was hungry, for a concrete, material thing, for food. This is a very old story, but it is eternally true.
