How does an Enlightened person view memories and the past

[Mike 03]

There is a saying from Master ZhouZou that I've struggled with for a couple of years that feels very relevant to where I am in practice:

The master entered the hall and said, "Brothers, simply remake what has gone by and work with what comes. If you do not remake, you are stuck deeply somewhere."

When Master ZhouZhou says "remake what has gone by" he seems to be saying something about how we deal with the past. What is the correct way to view memories? Memories, it seems to me, can yank us out of present awareness very quickly and reawaken the sense of there being a "self." Good memories create longing, nostalgia and attachment; bad memories create guilt and remorse. Does an enlightened person still have memories? Any opinions on "remaking what has gone by" are welcome.

He seems to say this is especially important, because if we can't do this we "are stuck deeply." I notice that I sometimes get stuck deeply by the past, so I want to figure out what he means.

Thank you!

Glad I found this group!
