...you cannot hold on to the past (con't).
It's not that the past doesn't (didn't), in some sense, exist. But, you have to let go of the form it took, so that which does live (did in the past, does in the present, will in the future) can be re-born.
Getting that (the living part) confused and holding onto the past prevents growth in the present—the re-generation of that life in the current time. In fact, not releasing the past kills the living part of it that remains.
This is why it has been said, to have eternal life, you must be born again.
I think this is true at all levels—from the personal to the collective.
...you cannot hold on to the past.
