KARMAYOGA
Karma yoga
The Bhagavad Gita gives a summary of the karma yoga process. The Gita itself is a chapter from the epic known as Mahabharata, wherein a dialogue takes place between the prince Arjuna, and his friend and chariot driver, Lord Krishna, on the brink of a great dynastic war. Their conversation is prompted by Arjuna as he is engulfed by sorrow and misgivings regarding the oncoming battle in which he has friends and relatives on both sides. In reply, Krishna then elucidates upon a number of philosophical yoga systems and practices by/through which he should indeed continue with the fight on righteous principles.The above text is a snippet from Wikipedia: Karma yoga
