I would like to ask pardon to you titlbillings
. Shame on me.
I have a mistake in my experiance, by confonding with satipatthana - the foundation of mindfulness.
It seems realy like foundation, stable, calm and free from body, feelings, mind, and mental events... Thats why this similies arise in my mind.
Foundation of mindfulness; frame of reference — body, feelings, mind, and mental events, viewed in and of themselves as they occur.
