Karma (from Sanskrit: "action, work") in Buddhism is the force that drives saṃsāra—the cycle of suffering and rebirth for each being, says Wikipedia.
Good, skillful deeds (Pāli: "kusala") and bad, unskillful (Pāli: "akusala") actions produce "seeds" in the mind which come to fruition either in this life or in a subsequent rebirth.[23]
The avoidance of unwholesome actions and the cultivation of positive actions is called śīla (from Sanskrit: "ethical conduct").
In Buddhism, karma specifically refers to those actions (of body, speech, and mind) that spring from mental intent ("cetana"),[24] and which bring about a consequence (or fruit, "phala") or result ("vipāka").
