Being absorbed in a task that is flowing well is to be in an enjoyable and selfless state, but one that is not sufficient unto itself. You want to come out of that state and collect the reward for it in self-consciousness, to gain the applause - but not necessarily literally, an internal gratification being enough, a harvesting of the good that arises as a surplus to the process you have been engaged in - to siphon off some of the enjoyment so that it infuses conscious self-reflection, so that self-reflection can take on positivity, so that you momentarily flash into existence. It is like Little Jack Horner, who not only enjoys his Christmas pie, but "put in his thumb,/and pulled out a plum,/ and said, 'What a good boy am I!'" The self, or the ego, that is confirmed in this way, that gains the substance of the "I am" is a contingent being in which you implicitly believe. It takes a certain effort, that is, a little dance of attention, to bring it about. Its contingency ought to render it suspect, purely illusory, but it is a baseline that you keep falling back to, a 'default mode'. Is it a way of ontologising enjoyment which otherwise seems to be cruelly subject to time? It doesn't solve that problem, but it does succeed in obscuring it, in preventing you from looking deeper into the dual question of enjoyment and being, or from wondering what kind of thing a 'self' is that it can appear to be the resolution of these divergent facts of experience.
