karma or karman , [Skt.,=action, work, or ritual], basic concept common to Hinduism , Buddhism , and Jainism . The doctrine of karma states that one's state in this life is a result of actions (both physical and mental) in past incarnations, and action in this life can determine one's destiny in future incarnations. Karma is a natural, impersonal law of moral cause and effect and has no connection with the idea of a supreme power that decrees punishment or forgiveness of sins. Karmic law is universally applicable, and only those who have attained liberation from rebirth, called mukti (or moksha ) or nirvana , can transcend it. Karma yoga (see yoga ), the spiritual discipline of detachment from the results of action, is a famous teaching of the Bhagavad-Gita .
