the varaah puraan. Here Narad muni talks to Yamraaj. LIBERATION FROM SINS

Narad asked Yamaraj about the reason why joy was so elusive to human beings. He
also wanted to know about the reasons for man's sorrows.

Yamaraj replied---Man's destiny is defined by his own actions. He has to taste the
fruits of his actions. He has to taste the fruits of his each and every actions. So when
a man finds himself amidst sorrows he must realize that he is reaping the fruits of
his past actions. If a man commits virtuous deeds then joy is experienced but sinful
deeds invite sorrows and miseries. Desires force a man to take countless birth. A
man takes birth on the basis of his past Karmas. God does not interfere in this
matter. So, only foolish people curse God for their miseries.They forget that their
sorrows are of their own making. A man can liberate himself from sins by engaging
in virtuous deeds and abstaining from sinful deeds. A man should perform his duties
with a sense of detachment,because attachment results into the transmigration of
the soul.
