How many hours of effort is necessary to earn the grace of the Divine?
You should pray to the Divine to give you the strength to bear all troubles and face all difficulties. If you have even an atom of grace of the Divine, a mountain of troubles can be overcome.
"If a fraction of the time that is spent in worrying about wealth, provisions, wife, children, friends and business, is devoted to contemplation on the feet of the Divine, one can face the messengers of death without fear and cross the ocean of samsara!"
It is not necessary to devote many hours to prayer. It is enough if one thinks of Him with all his heart and offers himself even for a few moments.
A single match stick when it is struck can dispel the darkness in a room that has remained closed for years. Mountains of cotton can be burnt down by a single spark.
Likewise, wholehearted chanting of His name even once, can destroy mountains of sins. But the chanting should not be done mechanically like playing a gramophone record. It should emanate from the depths of the heart.
- Divine Discourse, Apr 14, 1989.
Even if one small ray of the grace of the Divine falls on you, all your sins will be burnt away.
