Someone I know wrote this:
"Being thoroughly invested in what one is doing means identifying with one's state, which implies knowing what one's actual experience or situation is, and since nothing remains static, this also means identifying with the flow of one's states, trusting in the current of life (Yontef, 1993). As a figure of interest emerges from the situational background, the person identifies with that figure and becomes so invested, so immersed in it, that the background drops away and out of awareness (Perls, Hefferline, & Goodman, 1951)–even though it is always there to offer context for the interpretation of experience."
