कर्मण्येवाधिकारस्ते मा फलेषु कदाचन। मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि॥
karmanye vadhikaraste ma phaleshu kadachana ma karmaphala-hetur bhur ma te sango'stv akarmani
Translation
You have the right to perform your duty, but you are not entitled to the fruits of your actions. Never consider yourself to be the cause of the results, and never be attached to inaction.
Commentary
The single most famous verse of the Bhagavad Gita. It teaches the art of selfless action — do your duty with full dedication but without attachment to outcomes. This principle has inspired leaders, thinkers, and seekers for thousands of years.
