Hello Venerable Ajahn Doe, Hello Retro,
The question is about the mechanism that accumulates qualities such as wisdom or ignorance.
How does the mental quality that one has developed affect the future mental states?
If nothing is "carried", "accumulated" or "stored", then it is useless to develop anything as it will not affect anything in the future.
With best wishes,
