Hi 
Is there a fundamentally irreducible rūpa—one entirely incapable of further division—even whilst possessing spatial extension?
Naturally, we can imagine dividing spatial extensions ad infinitum. Yet, the mere capacity to conceptualise endless division does not dictate the definitive reality of the matter. Therefore, I would like to understand the precise arguments establishing why rūpa must ultimately reduce to a minimum, indivisible unit even whilst possessing spatial extension.
Many thanks all!
