If there is that ‘grasping moment, and ….grasped sankara become motivational forces for thinking, speech and acting’, how is it then that they ‘are not really me or mine’ and that it ‘ is a WRONG understanding at that moment they are grasped at as me or mine’? Naturally, ‘me and mine’ are understood as such only as far as our sansaric journey is concerned, as are the effects of those mental formations.
Moreover, I see no clear distinction between your points #1 and 2.
Perhaps you could clarify with illustrations.
