There are two kinds of peacefulness :
one is the peace that comes through samådhi,
the other is the peace that comes through paññå.
The mind that is peaceful through samådhi is still deluded.
The peace that comes through the practice of samådhi alone is dependent
on the mind being separated from mind-objects.
