Santhi (Peace) can also be defined as true love towards the
Lord, towards Truth itself and towards true dharma (Right
Action). Hence, it makes the realization of the Lord as your
sole aim. Hold fast to the desire to realize Him in this very
birth. Remain unaffected by lust or greed, by joy and pain,
praise and abuse or any such pair of opposites. Fortitude such
as this alone leads to Realization.
