The third chapter of the Bhagavad Gita is Karma Yoga or the Path of Selfless Service. Here Lord Krishna emphasizes the importance of karma in life. He reveals that it is important for every human being to engage in some sort of activity in this material world. Further, he describes the kinds of actions that lead to bondage and the kinds that lead to liberation. Those persons who continue to perform their respective duties externally for the pleasure of the Supreme, without attachment to its rewards get liberation at the end.
O scion of the Bharata dynasty, as the unenlightened people act with attachment to work, so should the enlightened person act, without attachment, being desirous of the prevention of people from going astray.OPEN VERSE
The enlightened man should not create disturbance in the beliefs of the ignorant, who are attached to work. Working, while himself remaining diligent, he should make them do all the duties.OPEN VERSE
While actions are being done in every way by the gunas (qualities) of Nature, one who is deluded by egoism thinks thus: 'I am the doer.'OPEN VERSE
But, O mighty-armed one, the one who is a knower of the facts about the varieties of the gunas and actions does not become attached, thinking thus: 'The organs rest (act) on the objects of the organs.'OPEN VERSE
Those who are wholly deluded by the gunas of Nature become attached to the activities of the gunas. The knower of the All should not disturb those of dull intellect, who do not know the All.OPEN VERSE
