It's all a mystery
It's so hackneyed: yesterday is gone; tomorrow is a mystery; and today is all you've got.
But, actually, this moment is all you've got and it's as rich and deeply mysterious as the projections and fantasies we give to the past and/or future.
To me (at least) the biggest ah-ha has been that every-thing is no more and no less than a moving, shifting, energetic experience — i.e. formless.
What it is, no one knows.
From that place of not knowing, I feel open to whatever happens — as Zorba said: the full catastrophe.
