Already did Lal and i got the impression that i was practicing right except point C) of my post. As for point A what i’m saying there is that i DON’T practice that.
Now in Bhavana Meditation i read that one can use as focus point a concept, you even recommend to start with Anicca so my question is: isn’t what i’m describing in point C the same practice ?
Anyways i’ll read again and i’ll submit here to your appreciation for correction a full scheme of formal practice from A to Z.
Thanks alot for the fine guidance.
