Karma is a important concept in Buddhism

Karma is a important concept in Buddhism.In a discourse (A.N. VI.63 Nibbedhika Sutta) the Buddha said:
Intention, monks, is karma I say. Having willed, one acts through body, speech and mind”.
According to the Buddha the moral order rests on each individual and not on any divine being:

"Owners of their own Karma, O young man, are living beings heirs of their Karma, have karma as the wombs from which they spring, having Karma as their refuge. Karma marks of living being, making them become depraved and excellent." (kammassakaa maa.nava sattaa, kammadaayadaa, kammayoni, kammabandhu kammapa.tisara.naa kamma.m satte vibhajati yadida.m hinappa.nitataaya. Cuulakammavibhaagasutta.)

In Buddhism, Karma has a specific meaning quite different from other teachings. Karma means action derived from mental intent or volition and its result (Vipaka) or its effect upon the doer of that volitional deed (be that deed one of thought, word or physical action).
