"At the very instant that you think, "I am happy," a chemical messenger translates your emotion, which has no solid existence whatever in the material world, into a bit of matter so perfectly attuned to your desire that literally every cell in your body learns of your happiness and joins in."

You can have lots of feelings and have the same feelings over and over again. It isn't the recognizable feelings that make so much difference. It is sensing the edge, the unclear, what you don't recognize, but it is there, the bodily discomfort that the problem makes, which has meaning; it has its own peculiar quality, implicity, it is complex, it has in it everything that relates to that problem, but not in a way you can say.
