The Self is just one big question mark. I'm not talking about the elusive nature of the self that compels us to ask "What is the self (or Self)?" For the purposes of this discussion, by the way, I'm not going to differentiate between the big-S Self and the small-s self. Let's pretend there's just one Self. And I say, that Self is just one big question mark.
And who am I to say that? The Self. Ask yourself instead who are you to question me? The Self as well, you big question mark.
Okay, having established that, what is the question? Is it "to be or not to be"? Let's say that Hamlet wasn't actually talking about the advisability of living vis-a-vis dying, in other words wasn't a contemplation of suicide as that soliloquy is usually interpreted. Maybe he was talking about the the nature of the Self's question. Maybe that's why that soliloquy resonates so much, because of the absolute universality of its theme.
So the Self is asking, first and foremost, should It Be, or not? And upon the answer depends whether material creation itself will come into manifestation.
What was the answer? Maybe the answer is the universe itself. And if you believe there is no universe, just a maze of illusion and a lot of ghostly selves stumbling around in it, the thing that remains, without question, is the Question, eternally hanging.
If you don't answer it, who will?
