If you are
working for Krsna, it is Krsna's desire if you be successful or not successful.
Here it is, the word is used, asiddhau. That means don't think that because you
are Krsna conscious, you will be always successful. No. It doesn't matter.
Even
if you are unsuccessful, you must know it firmly that without Krsna's desire,
nothing can happen. If you are unsuccessful, then you should.... That is Krsna
conscious.... You should know also that "It is Krsna's desire." It is
Krsna's desire.
So there is no question of being depressed because you are
unsuccessful. A devotee is never depressed in the horrible condition of life.
Tat te 'nukampam su-samiksamano bhunjana... [SB 10.14.8].
