Karma (Sanskrit: कर्म; IPA: [ˈkərmə]; Pali: kamma) means action, work or deed; it also refers to the spiritual principle of cause and effect where intent and actions of an individual (cause) influence the future of that individual (effect). Good intent and good deed contribute to good karma and future happiness, while bad intent and bad deed contribute to bad karma and future suffering. Karma is closely associated with the idea of rebirth in many schools of Asian religions. In these schools, karma in the present affects one's future in the current life, as well as the nature and quality of future lives - one's saṃsāra.
With origins in ancient India, karma is a key concept in Hinduism, Buddhism, Jainism, Sikhism, and Taoism.
Karma is the executed "deed", "work", "action", or "act", and it is also the "object", the "intent". Halbfass explains karma (karman) by contrasting it with another Sanskrit word kriya. The word kriya is the activity along with the steps and effort in action, while karma is (1) the executed action as a consequence of that activity, as well as (2) the intention of the actor behind an executed action or a planned action (described by some scholars as metaphysical residue left in the actor). A good action creates good karma, as does good intent. A bad action creates bad karma, as does bad intent.
Karma, also refers to a conceptual principle that originated in India, often descriptively called the principle of karma, sometimes as the karma theory or the law of karma. In the context of theory, karma is complex and difficult to define. Different schools of Indologists derive different definitions for the karma concept from ancient Indian texts; their definition is some combination of (1) causality that may be ethical or non-ethical; (2) ethicization, that is good or bad actions have consequences; and (3) rebirth. Other Indologists include in the definition of karma theory that which explains the present circumstances of an individual with reference to his or her actions in past. These actions may be those in a person's current life, or, in some schools of Indian traditions, possibly actions in their past lives; furthermore, the consequences may result in current life, or a person's future lives. The law of karma operates independent of any deity or any process of divine judgment.
