memories that arise in the mind, memories of long ago: these are classified under sankhara-khanda, yes?
Here is where I'm a bit confused. A memory arises, which is a 'formation', a 'mental fashioning'. But I can have either a pleasant feeling associated with
that memory, or a painful feeling, or a neutral feeling. So - the memory itself
is sankhara, but the feeling(s) that come up alongside it
are vedana, yes?
For example, we might remember being a child, walking in the yard of our home. Recollecting that, there is a happy feeling. The memory and the happy feeling seem to arise together, but they are actually separate things, are they not?
