Karma means action, means "to do". Immediately we have an indication that the real meaning of karma is not fate because karma is action. It is dynamic. But it is more than simply action because it is not mechanical action. It is not unconscious or involuntary action. It is intentional, conscious, deliberate, willful action. How is it that this intentional, will action conditions or determines our situation? It is because every action must have a reaction, an effect. This truth has been expressed in regard to the physical universe by the great physicist Newton who formulated the law which states that every action must have an equal and opposite reaction. In the moral sphere of conscious actions, we have a counterpart to the physical law of action and reaction, the law that every intentional, will action must have its effect. This is why we sometimes speak either of Karma-Vipaka, intentional action and its ripened effect, or we speak of Karma-Phala, intentional action and its fruit. It is when we speak of intentional action together with its effect or fruit that we speak of the Law of Karma.
In its most basic sense, the Law of Karma in the moral sphere teaches that similar actions will lead to similar results. Let us take an example. If we plant a mango seed, the plant that springs up will be a mango tree, and eventually it will bear a mango fruit. Alternatively, if we plant a Pong Pong seed, the tree that will spring up will be a Pong Pong tree and the fruit a Pong Pong. As one sows, so shall one reap. According to one’s action, so shall be the fruit. Similarly, in the Law of Karma, if we do a wholesome action, eventually we will get a wholesome fruit, and if we do an unwholesome action eventually we will get an unwholesome, painful result. This is what we mean when we say that causes bring about effects that are similar to the causes. This we will see very clearly when we come to specific examples of wholesome and unwholesome actions.
We can understand by means of this general introduction that karma can be of two varieties - wholesome karma or good karma and unwholesome karma or bad karma. In order that we should not misunderstand this description of karma, it is useful for us to look at the original term. In this case, it is kushala or akushala karma, karma that is wholesome or unwholesome. In order that we understand how these terms are being used, it is important that we know the real meaning of kushala and akushala. Kushala means intelligent or skilful, whereas akushala means not intelligent, not skilful. This helps us to understand how these terms are being used, not in terms of good and evil but in terms of skilful and unskilful, in terms of intelligent and unintelligent, in terms of wholesome and unwholesome. Now how wholesome and how unwholesome? Wholesome in the sense that those actions which are beneficial to oneself and others, those actions that spring not out of desire, ill-will and ignorance, but out of renunciation, loving-kindness and compassion, and wisdom.
One may ask how does one know whether an action that is wholesome or unwholesome will produce happiness or unhappiness. The answer is time will tell. The Buddha Himself answered the question. He has explained that so long as an unwholesome action does not bear its fruit of suffering, for so long a foolish person will consider that action good. But when that unwholesome action bears its fruit of suffering then he will realize that the action is unwholesome. Similarly, so long as a wholesome action does not bear its fruit of happiness, a good person may consider that action unwholesome. When it bears its fruit of happiness, then he will realize that the action is good. So one needs to judge wholesome and unwholesome action from the point of view of long-term effect. Very simply, wholesome actions result in eventual happiness for oneself and others, while unwholesome actions have the opposite result, they result in suffering for oneself and others.
Specifically, the unwholesome actions which are to be avoided relate to the three doors or means of action, and these are body, speech and mind. There are three unwholesome actions of the body, four of speech and three of mind that are to be avoided. The three unwholesome actions of body that are to be avoided are killing, stealing and sexual misconduct. The four unwholesome actions of speech that are to be avoided are lying, slander, harsh speech and malicious gossip. The three unwholesome actions of mind that are to be avoided are greed, anger and delusion. By avoiding these ten unwholesome actions we will avoid their consequences. The unwholesome actions have suffering as their fruit. The fruit of these unwholesome actions can take various forms. The fully ripened fruit of the unwholesome actions consists of rebirth in the lower realms, in the realms of suffering — hell, hungry ghosts and animals. If these unwholesome actions are not sufficient to result in rebirth in these lower realms, they will result in unhappiness in this life as a human being.
Here we can see at work the principle of a cause resulting in a similar effect. For example, habitual killing which is motivated by ill-will and anger and which results in the taking of the life of other beings will result in rebirth in the hells where one’s experience is saturated by anger and ill-will and where one may be repeatedly killed. If killing is not sufficiently habitual or weighty to result in rebirth in the hells, killing will result in shortened life as a human being, separation from loved ones, fear or paranoia. Here too we can see how the effect is similar to the cause. Killing shortens the life of others, deprives others of their loved ones and so forth, and so if we kill we will be liable to experience these effects. Similarly, stealing which is borne of the defilement of desire may lead to rebirth as a hungry ghost where one is totally destitute of desired objects. If it does not result in rebirth as a ghost, it will result in poverty, dependence upon others for one’s livelihood and so forth. Sexual misconduct results in marital distress or unhappy marriages.
While unwholesome actions produce unwholesome results - suffering, wholesome actions produce wholesome results - happiness. One can interpret wholesome actions in two ways. One can simply regard wholesome actions as avoiding the unwholesome actions, avoiding killing, stealing, sexual misconduct and the rest. Or one can speak of wholesome actions in positive terms. Here one can refer to the list of wholesome actions that includes generosity, good conduct, meditation, reverence, service, transference of merits, rejoicing in the merit of others, hearing the Dharma, teaching the Dharma and straightening of one’s own views. Just as unwholesome actions produce suffering, these wholesome actions produce benefits. Again effects here are similar to the actions. For example, generosity results in wealth. Hearing of the Dharma results in wisdom. The wholesome actions have as their consequences similar wholesome effects just as unwholesome actions have similar unwholesome effects.
Karma, be it wholesome or unwholesome, is modified by the conditions under which the actions are performed. In other words, a wholesome or unwholesome action may be more or less strong depending upon the conditions under which it is done. The conditions which determine the weight or strength of karma may be divided into those which refer to the subject — the doer of the action — and those which refer to the object — the being to whom the action is done. So the conditions that determine the weight of karma apply to the subject and object of the action. Specifically, if we take the example of killing, in order for the act of killing to have its complete and unmitigated power, five conditions must be present — a living being, the awareness of the existence of a living being, the intention to kill the living being, the effort or action of killing the living being, and the consequent death of the living being. Here too, we can see the subjective and the objective conditions. The subjective conditions are the awareness of the living being, the intention to kill and the action of killing. The objective conditions are the presence of the living being and the consequent death of the living being.
Similarly, there are five conditions that modify the weight of karma and they are persistent, repeated action; action done with great intention and determination; action done without regret; action done towards those who possess extraordinary qualities; and action done towards those who have benefited one in the past. Here too there are subjective and objective conditions. The subjective conditions are persistent action; action done with intention; and action done without regret. If one does an unwholesome action again and again with great intention and without regret, the weight of the action will be enhanced. The objective conditions are the quality of the object to whom actions are done and the nature of the relationship. In other words, if one does a wholesome or unwholesome action towards living beings who possess extraordinary qualities such as the arhats, or the Buddha, the wholesome or unwholesome action done will have greater weight. Finally the power of wholesome or unwholesome action done towards those who have benefited one in the past, such as one’s parents, teachers and friends, will be greater.
The objective and subjective conditions together determine the weight of karma. This is important because understanding this will help us to understand that karma is not simply a matter of black and white, or good and bad. Karma is moral action and moral responsibility. But the working of the Law of Karma is very finely tuned and balanced so as to match effect with cause, so as to take into account the subjective and objective conditions that determine the nature of an action. This ensures that the effects of actions are equal to and similar to the nature of the causes.
The effects of karma may be evident either in the short term or in the long term. Traditionally we divide karma into three varieties related to the amount of time that is required for the effects of these actions to manifest themselves. Karma can either manifest its effects in this very life or in the next life or only after several lives. When karma manifests its effects in this life, we can see the fruit of karma within a relatively short length of time. This variety of karma is easily verifiable by any of us. For instance, when someone refuses to study, when someone indulges in harmful distractions like alcohol and drugs, when someone begins to steal to support his harmful habits; the effects will be evident within a short time. They will be evident in loss of livelihood and friendship, health and so forth. We cannot see the long-term effect of karma, but the Buddha and His prominent disciples who have developed their minds are able to perceive directly the long-term effects. For instance, when Maudgalyayana was beaten to death by bandits, the Buddha was able to tell that this event was the effect of something Maudgalyayana had done in a previous life when he had taken his aged parents to the forest and having beaten them to death, had then reported that they had been killed by bandits. The effect of this unwholesome action done many lives before was manifested only in his last life. At death we have to leave everything behind — our property and our loved ones, but our karma will accompany us like a shadow. The Buddha has said that nowhere on earth or in heaven can one escape one’s karma. So when the conditions are correct, dependent upon mind and body, the effects of karma will manifest themselves just as dependent on certain conditions a mango will appear on a mango tree. We can see that even in the world of nature certain effects take longer to appear than others. If for instance, we plant the seed of a papaya, we will obtain the fruit in shorter period than if we plant the seed of a durian. Similarly, the effects of karma manifest either in the short term or in the long term.
Besides the two varieties of karma, wholesome and unwholesome karma, we should mention neutral or ineffective karma. Neutral karma is karma that has no moral consequence either because the very nature of the action is such as to have no moral consequence or because it is done involuntarily and unintentionally. For example, sleeping, walking, breathing, eating, handicraft and so forth in themselves have no moral consequence. Similarly, unintentional action is ineffective karma. In other words, if one accidentally steps on an insect, being unconscious of its existence, this also constitutes neutral karma because there is no intention - the intentional element is not there.
The benefits of understanding the Law of Karma are that this understanding discourages one from performing unwholesome actions which have suffering as their fruit. Once we understand that in our own life every action will have a similar and equal reaction, once we understand that we will experience the effect of that action, wholesome or unwholesome, we will refrain from unwholesome behavior, not wanting to experience the effects of these unwholesome actions. And similarly, understanding that wholesome actions have happiness as their fruit, we will cultivate these wholesome actions. Reflecting on the Law of Karma, of action and reaction in the moral sphere encourages us to renounce unwholesome actions and cultivate wholesome actions.
