Rudra Vaishnava Sampradaya - Commentary





Here Lord Krishna commences with tapah or austerities  that  exemplify  raja
guna  the  mode  of  passion.  The  occasional  enacting   of   ostentatious
austerities for the hope of receiving praise,  salutations  and  acclamation
with a covert desire for prestige, honour  and  wealth  results  in  rewards
that are temporary, unstable and transient. Even if following perfectly  the
ordinances and injunctions of the  Vedic  scriptures  such  austerities  are
merely situated in raja guna.


Brahma Vaishnava Sampradaya - Commentary
