Premanand Maharaj Ji
How do I stop worrying?
You own the action, not the fruit
Bhagwan said that you have a right to action, not to its fruit. Fixing the result in advance, and then not getting it, brings disappointment and worry.
"Karmanye vadhikaraste ma phaleshu kadachana": you hold the right over action, not over the fruit. Only do the action. Our mistake is that we fix the fruit first.
