Some ideas I recently read/thought about I thought I'd share: Forget about everything you identify "yourself" with (name, profession, etc), realize that it all comes down to a single awareness of reality as it happens around you (some refer to this as ego-death or ego-loss). Every living creature shares the same capacity to experience reality as everyone else, i.e. they all experience it, it just so happens that we're biologically capable of observing the experience of reality (rather than just living it). In accordance with science and the deterministic nature of the universe, reality unfolds and "we" are merely observing it. This may suggest a kind of symbolic or spiritual or literal unified consciousness or awareness throughout existence--so it may be totally symbolic or it may be a non-physical life giving force that we are biologically suited to recognize. We can only speculate. So whatever the "truth" may be hardly matters, as reality exists only as we perceive it.
