In Buddhism, kamma refers to volitional actions and their results (vipaka). Kamma is generated by the prevailing conscious mind and results in discernible reactions through the subtle conscious mind. The prevailing mind is responsible for decision making and actions, while the subtle mind attracts similar vibrational frequencies based on those actions. As humans have both prevailing and subtle conscious minds, the human realm is where new kamma is often initiated through choice and resolution of past kamma. It is important for humans to live wholesome lives guided by wisdom rather than ignorance, in order to avoid regret and attain opportunities to learn.
