There's a passage and Digha Nikaya 15 where the Buddha lists the various ways in which self can be defined; either as having a form and finite, having a form and infinite, formless and finite, formless and infinite, that pretty much covers all the ground. So each of those cases, you can say either the self already is that way, or it can be made to be that way, or it will naturally become that way, say when you go to sleep, or when you when you die. So those three modes times four types of self gives you 12 self views that you can go for, and the Buddha puts them all aside. He says that when you look at the way they define the self and none of them are really worth going with. Now notice that it's a value judgment he's making here. I want to make this point again and again throughout the day. That the Buddha is less interested in talking about what you are- but talking about the value of judgment of whether something is worth claiming to be self or not self. So the consequences of saying no, there is no self winding around up with a question about; "Well, who's doing the practice, then, and who are we doing this for?" There was a study made years back of infant behavior. And the psychologist noticed that one of the things that makes children the happiest, especially little tiny children, is when they figure out they can do something, and they get a result. And they do it again, and they get the same result. And this is why children start banging away on something drives you crazy. But for them, it's not just the sound. It's the fact that they've learned something about causality, they've learned something that they have some power to have an influence on their environment. And this is the main source of delight for infants. We'll see that this sense of agency is going to be important for doing the path. Because as the Buddha said, you want to be able to delight in abandoning unskillful qualities and to delight in developing skillful qualities. This quality delight does not happen when you feel that you are powerless to make a difference. In fact, if you feel like you're powerless, you cannot make a difference through your choices, it leads to depression. Whereas the Buddhist making this sense that the path to the end of suffering has to be a path that you delight in.
