Yoga of action. (Glossary for the Vahinis)

When an action is performed without desire and without any feeling of egoism, then it may be called Karma Yoga. Remove your desire for the fruit. When you perform action with this attitude, it becomes a Yajna, it becomes work in spirit of true sacrifice, it becomes Tapas or penance, and it becomes Yoga; all three of these Yajna, Tapas and Yoga convey the same idea. Every action performed by man should be sanctified in this way. (DBG, p. 222)
