Shri Vaishnava Sampradaya - Commentary


A peaceful mind means a mind immovably situated  in  constant  mediation  on
the atma or soul. Once this is accomplished it is  quite  natural  that  the
yogi  or  one  perfecting  the  science  of  the  individual   consciousness
attaining communion with the ultimate consciousness by dhyana or  meditation
soon has all blemishes and sins completely purged. The  words  santa-rajasam
means the quality of  rajas or passion has become santa or  peaceful.  Hence
one  becomes  imbued  with  the  qualities  of  the  Brahmam  or   spiritual
substratum pervading all existence and which also refers to the atma and re-
establishs one into their true essence of spiritual  splendour.  To  such  a
yogi comes atma  tattva  or  realisation  of  the  soul  and  exquisite  and
phenomenal transcendental  felicity.  The  word  used  by  Lord  Krishna  hi
meaning verily, is an indeclinable particle which gives  a  reason  denoting
that by the reason of  atma  tattva  being  essentially  blissful  the  yogi
becomes blissful as well.
