I'm wondering about this.
At a vihara in Queens, NY, the elder bhikkhu was giving the damma talk.and as i was listening i had the thought:
How many kinds of memory are there?
at this he said, "and you will have sublime thoughts."
Somehow i seem drawn to issue, it seems "prescient" in my life.
Earlier i thought, good/bad would be normal categories of memory. When i share with people, particularly with whom i "share memories," notions of path seem to become fuzzy or no longer relevant in the same way. In some ways sharing "opens up the sphere."
Meditative memory (along with some recollection) are certainly different from crossword puzzle type, though.
