The Bhagavad Gita originated from the dialogue between Lord Krishna and Arjuna at Kurukshetra. In the second Adhyay, Lord Krishna imparts the famous Shloka: “karmanye vadhikaraste ma phaleshu kadachana (कर्मण्येवाधिकारस्ते मा फलेषु कदाचन। मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि॥)”. This verse encapsulates the essence of Karma Yoga. Sri Guru elaborates on the four principles of Karma Yoga from the Bhagavad Gita in this video.
