We know that what binds us in samsara are the defilements - desire, ill-will and ignorance. We spoke about this when we talked about the Second Noble Truth - the truth of the cause of suffering. These defilements are something which every living being in samsara shares, whether we speak of human beings or animals or beings who live in the other realms which we do not normally perceive. In this, all living beings are alike and yet amongst all the living beings that we can normally perceive, there are many differences. For instance, some of us are wealthy, some are less wealthy, some are strong and healthy, others are disabled and so forth. There are many differences amongst living beings and even more so there are differences between animals and human beings. These differences are due to karma.

What we all share - desire, ill-will and ignorance - are common to all living beings, but the particular condition in which we find ourselves is the result of our particular karma that conditions the situation in which we find ourselves, the situation in which we may be wealthy, strong and so forth. These circumstances are decided by karma. It is in this sense that karma explains the differences amongst living beings. It explains why some beings are fortunate while others are less fortunate, some are happy while others are less happy. The Buddha has specifically stated that karma explains the differences between living beings. You might also recall that the understanding of how karma affects the birth of living beings in happy or unhappy circumstances - the knowledge of how living beings move from happy circumstances to unhappy circumstances, and vice versa, from unhappy to happy circumstances as a result of their karma - was part of the Buddha’s experience on the night of His enlightenment. It is karma that explains the circumstances that living beings find themselves in.

Having said this much about the function of karma, let us look more closely at what karma is. Let us define karma. Maybe we can define karma best by first deciding what karma is not. It is quite often the case that we find people misunderstanding the idea of karma. This is particularly true in our daily casual use of the term. We find people saying that one cannot change one’s situation because of one’s karma. In this sense, karma becomes a sort of escape. It becomes similar to predestination or fatalism. This is emphatically not the correct understanding of karma. It is possible that this misunderstanding of karma has come about because of the popular idea that we have about luck and fate. It may be for this reason that our idea of karma has become overlaid in popular thought with the notion of predestination. Karma is not fate or predestination.

If karma is not fate or predestination, then what is it? Let us look at the term itself. 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 martial distress or unhappy marriages.
