New mind is arising all the time. Every experience is always new. We cannot experience the old experience twice.
If we think that it is old one, it has become a concept.
We think memory is the past, but thinking mind is present – story is a concept; the mind is reality.
The story – memory or planning - may be about the past or future, but the mind is always new.
Sometimes memory comes back, and we say again, and again, but actually memory mind is arising and new. B
