Within the last few weeks I also came to the point where the concept of a “mind” is just a worldly idea (pannatti). There is only rupa sensed by the citta/cetasika and corresponding sankhara are carried out. With this one can creep closer to a deeper understanding about existence and how useless it is to do (abhi)sankhara in order to achieve something in the world. Also any thinking about future or past will worry the “mind”. There can no peace be gained. But before reaching such a stage one has to analyse the dhamma and needs hints and proof to establish saddha/panna.
