Niṣkāma karma is action free from desire for its fruits, the central teaching of the Bhagavad Gītā’s way of action. One has a right to the work, not to the results. Done in this spirit, action does not bind and purifies the mind. The teaching was taken up in modern times by Vivekananda, Tilak and Gandhi.
Niṣkāma karma
Desireless action: work done as duty or offering, without attachment to its results.
