Twenty hammer-strokes might not succeed in breaking a stone, the 21st
stroke might break it. But does that mean that the 20 blows were
of no avail? No, each of those 20 strokes contributed its share
to the final success. The final result was the cumulative effect
of all the 21. Infuse every moment of your life with Love for
God. Then, evil tendencies will not hamper your path. The
object of all spiritual practices is the destruction of the mind and
some day, one good deed will succeed in destroying it. This
triumph is the result of all the good deeds done in the past. So
never give up, and no good deed will be a waste!
