Karma literally means action or doing. Any kind of intentional action whether mental, verbal, or physical, is regarded as Karma. It covers all that is included in the phrase "thought, word and deed". Generally speaking, all good and bad action constitutes Karma. In its ultimate sense Karma means all moral and immoral volition. Involuntary, unintentional or unconscious actions, though technically deeds, do not constitute Karma, because volition, the most important factor in determining Karma, is absent.
