How does Dimmesdale's perspective change in this chapter? chapter 20

After his interaction with Pearl at the stream, Dimmesdale returns to town thoroughly aware of having a new perception of life. He has much more energy than when he left only two days earlier, and everything looks different to him. Three times in a row he is approached by various people, and he struggles not to utter blasphemy. He is even tempted to teach dirty words to a group of small Puritan children.
