One is unable to stand still even for a moment! Absence of mere
anger cannot be taken as peace. The winning of a desired object
should not be confused with santhi (peace). Prasanthi
is that, which when it pervades the heart and cannot be shaken
subsequently for any reason. That type of peace alone deserves
to be called Prasanthi. Prasanthi has no ups
and downs, it cannot be partial in adversity and complete in
prosperity. It cannot be one thing today and another tomorrow.
Maintaining the same even flow of bliss, joy, always, is
Prasanthi, supreme peace.
