The connection between consciousness and being, Dasein and Sein, or Seyn, is both the basis of all philosophy and rather obscure at the same time. For something that is the very basis of evidence it is irritatingly far from self-evident. One way out is that consciousness is not what it is, but rather, at least mostly, a fallen and inauthentic version of itself. It an't quite be that simple since consciousness can only be what it is and so complete in each moment. Its essence must only be somehow concealed from itself, but present in a mysterious identity, as the non-distinction of samsara and nirvana. Consciousness is lost in representation, but representation is only possible because there is presentation, and the faintest hint of difference that still might haunt presentation can only be because of some even more original identity. It is as if you are always living somewhere out in front of yourself, the illusion of which can only be if you are always only where you actually are, right there at yourself.
