Premanand Maharaj Ji
How should I approach my job and work?
Karmanye vadhikaraste: act, don't fix the result
Bhagwan said that your right is to action alone and not to its fruit. Fixing the result beforehand brings disappointment and worry, so do the duty and leave the result to Bhagwan.
Bhagwan said, "Karmanye vadhikaraste ma phaleshu kadachana." You have a right over action, not over its fruit. You only do the karma.
