When you weren't thinking about it, suddenly the answer has come to you, as a present from the gods．You're pleased with it, and feel good．It may not be right, but at least you can try it out．Of course all ideas don't come like that, but the interesting thing is that so many do, particularly the most important one．They come into the mind, glowing（燃烧）with the heat of creation．
