Lord Krishna explains the significance of selfless action. Arjuna, still reluctant to fight, asks why Krishna is encouraging action if knowledge is superior. In response, Krishna emphasizes that everyone must perform their duties and fulfill their roles in society without attachment to the results. He introduces the concept of Karma Yoga, urging Arjuna to act in accordance with his Kshatriya duty as a warrior, but with detachment, dedicating his actions to the divine. By practicing Karma Yoga, one can avoid the bondage of karma and attain spiritual liberation, harmonizing action with inner peace.
