[Dialogue] Question about Kierkegaard

I keep remembering "The self is a relation; that relates itself to itself; and in willing to be that relation; grounds itself transparently in the power that posits it." And I remember the diagram with the lines and boxes and curvy arrows. Where did that come from (which book or paper?). What was SK pointing to? What were we pointing to? I am afeared that I am misusing it. Thanks. Jim Wiegel “We are all time travelers journeying into the future. But let us make that future a place we want to visit. “ Stephen Hawking
