The law of karma is one of the most important laws governing our lives. When we understand it, and live our understanding, when we act on what we know, then we experience a sense of wholeness and peace.
Karma is a Sanskrit word (kamma in Pali) that means “action.” The law of karma refers to the law of cause and effect: that every volitional act brings about a certain result. If we act motivated by greed, hatred, or delusion, we are planting the seed of suffering; when our acts are motivated by generosity, love, or wisdom, then we are creating the karmic conditions for abundance and happiness. An analogy from the physical world illustrates this: if we plant an apple seed, the tree that grows will bear apples, not mangos. And once the apple seed is planted, no amount of manipulation or beseeching or complaining will induce the tree to yield a mango. The only meaningful action that will produce a mango is to plant a mango seed. Karma is just such a law of nature, the law of cause and effect on the psychophysical plane.
The Buddha used the term karma specifically referring to volition, the intention or motive behind an action. He said that karma is volition, because it is the motivation behind the action that determines the karmic fruit. Inherent in each intention in the mind is an energy powerful enough to bring about subsequent results. When we understand that karma is based on volition, we can see the enormous responsibility we have to become conscious of the intentions that precede our actions. If we are unaware of the motives in our minds, when unskillful volitions arise we may unmindfully act on them and thus create the conditions for future suffering.
The law of karma can be understood on two levels, which indicate the vast scope of its implications in our lives. On one level, karma refers to the experience of cause and effect over a period of time. We perform an action, and sometime later we begin to experience its results. We plant a mango seed, and many years later we taste the fruit. The other level of understanding karma has to do with the quality of mind in the very moment of action. When we experience a mind state of love, there comes naturally along with it a feeling of openness and joy that is its immediate fruit; similarly, when there are moments of greed or hatred, in addition to whatever future results will come, we also experience the painful energies that arise with those states. Our direct awareness of how the karmic law is working in each moment can be a strong motivation to develop skillful states of mind that create happiness for us in the moment, as well as produce the fruit of well-being in the future.
Another dimension of the law of karma helps in understanding how individual personalities develop. While it is true that there is no enduring entity, no unchanging self that can be called “I,” it is also quite obvious that each of us is a uniquely changing and recognizable pattern of elements. This comes about because each of us has in our own way, both consciously and unconsciously, cultivated different mind states. If we cultivate loving-kindness, we experience its taste in the moment and at the same time are strengthening it as a force in the mind, making it easier for it to arise again. When we are angry, we experience the suffering of that anger as present karma and are also strengthening that particular pattern of mind. Just as we condition our bodies in different ways through exercise or lack of it, so we also condition our minds. Every mind state, thought, or emotion that we experience repeatedly becomes stronger and more habituated. Who we are as personalities is a collection of all the tendencies of mind that have been developed, the particular energy configurations we have cultivated.
We tend not to pay attention to this conditioning factor of our experience, thinking instead that once an experience has passed it is gone without residue or result. That would be like dropping a stone in water without creating any ripples. Each mind state that we experience further conditions and strengthens it.
The great inspiration of the Buddha’s teaching is that we must each take ultimate responsibility for the quality of our lives. Given certain volitional actions, certain results will follow. When we understand that our lives are the unfolding of karmic law, that we are the heirs to our own deeds, then there grows in us a deepening sense of responsibility for how we live, the choices we make, and the actions we undertake.
