Certain kinds of poison can take effect immediately; others may take months or even years for the effect to set in. The same is true of karmic results. Although we cannot see the actual workings of cause and effect, the manifestation of effect follows the same principle. If people see that a person remains in good health after taking poison but before the effect setting in, they then assume that the person did not take poison after all. Does this make sense? In fact, one should not equate absence of pain with non-poison; it is simply not time yet for the poison to take effect. Similarly, killing and stealing are like swallowing poison. They are bound to take effect, just a matter of time.

Also stated in the Abhidharma-kosha-shastra is that some children may suffer the effect of seriously negative karma that their parents accumulated. If children can suffer the consequences of their parents’ negative karma, is it not contradictory to the Buddhist teaching that one reaps what one sows and that no one can assume other’s karma? The Abhidharma-kosha-shastra explains that these children themselves already have certain negative karma. Due to the close relationship between the parents and their children, the ripening of the children’s negative karma may be expedited when the parents committed extremely evil karma.

It is stated in the scriptures that ripening of the cause comes in four types. The first is the one that ripens in the same lifetime. For example, karma was committed in youth and the effect takes place in middle or old age. Sometimes karma ripens even sooner, and the effect can be seen immediately. The reason is that certain conditions can expedite the manifestation of fruit. Such fast ripening has something to do with the object and the motivation of the action. There are many such cases told in One Hundred Stories about Karma (Karmasakata). For example, the Sangha and ordinary people are two completely different objects. If it is a serious case of stealing from or slandering the Sangha, the retribution may come right away or in this lifetime. If the same act is committed against ordinary people, one will surely bear the consequence but not necessarily right away or in this lifetime. The different results arise from the difference between the two objects. The other condition is the difference in motivation. If the intention to kill is very strong or has been premeditated for a long time, the retribution will come swiftly, whereas the effect may not be immediately apparent if the motivation to kill is not so fierce.

The second is the effect of committing great evil, such as the five hellish deeds, or great virtue will definitely materialize in the next life.The third effect is certain to manifest but the timing of which is uncertain; it may take three or four lifetimes or even longer. The fourth, there may or may not be any effect. What could be the reason for this uncertainty in view of infallible karma? When a weak cause (or karma) encounters a strong antidote, causality may then be broken.

The first three types of karma, that is, the one that ripens in this and next life, and with uncertain timing, are immutable karma. The fourth, with indefinite fruition, is mutable karma.

During the time of the Buddha, there were many non-Buddhist practitioners in India who, with their clairvoyance, saw lifelong virtuous people find rebirth in the hell, hungry ghost, or animal realm instead. They questioned, “If cause and effect was truly infallible, why would virtuous people not end up well?” Hence, they viewed the idea of cause and effect as pure nonsense.

How can a person who has practiced virtue the entire life be reborn in the lower realms? Well, although the person may have been virtuous throughout this life, we do not know anything about this person’s previous lives. Maybe the person has been virtuous in this as well as the last two lifetimes, but it may not be so anymore if we could go back even further. Some negative karma might have been committed many lifetimes ago. From the perspective of the three types of immutable karma, virtuous karma that the person has committed in this life happens to ripen not in the current or the next life, but in the yet known future lives. That is, it may not come to fruition until perhaps hundreds or even thousands of years later.

In our innumerable past lives, had we ever committed this type of immutable karma? The answer is yes. Therefore, we can be as virtuous as we would like in this life, retribution may still await us if we cannot purify all our negative karma of the past. Once this type of karma matures, there is no escape but to bear its effect albeit temporarily. Does this mean that virtuous karma we have accumulated in this lifetime will go to waste? It certainly won’t. They also bear their own fruit. However, if virtuous karma is not powerful enough and ripens slowly, it is possible that we may have to suffer first before enjoying any reward.

Some people think that it is because killing and stealing are against religious beliefs that people refrain from doing so. The truth is that killing and stealing should be forsaken because they are against the natural law and hence inevitable punishment. For example, is it against the Buddhist doctrine to take poison? Although Buddhism forbids people to take poison, the real reason is poison itself which is inedible. If you insist on taking it, you will be poisoned and experience pain. This is the result of acting against the natural law. Certain kinds of poison can take effect immediately; others may take months or even years for the effect to set in. The same is true of karmic results. Although we cannot see the actual workings of cause and effect, the manifestation of effect follows the same principle. If people see that a person remains in good health after taking poison but before the effect setting in, they then assume that the person did not take poison after all. Does this make sense? In fact, one should not equate absence of pain with non-poison; it is simply not time yet for the poison to take effect. Similarly, killing and stealing are like swallowing poison. They are bound to take effect, just a matter of time.

When ink is poured on the snow, the snow will be turned into ink color. After it melts, the color can still be seen on the ground. Similarly, if karma is born of defilements, the karmic mark will be left in the alaya consciousness after defilements are gone. Karma (or cause) is kind of a unique ability. Although our eyes cannot see how rice seeds germinate, they do have within themselves the capacity to do so. Likewise, when a karmic seed is planted in the alaya consciousness, it will yield fruit when all the right conditions come together. This fruit is also called karmic effect. And this particular capacity of the alaya consciousness to yield karmic fruit is the inherent nature of cause.

when there is cause, there is effect. Life’s sorrows and joys, separations and reunions, in fact, all phenomena come with their own respective causes. Some we can see, some cannot. Only very special kind of persons can grasp the whole picture. But cause and effect always go hand in hand, never alone. No cause, no effect, and vice versa. If one is in pursuit of happiness, one must sow happiness to reap happiness. The seed of happiness is virtuous action. To avoid suffering and misfortune, one must not give rise to their causes. The cause of suffering is doing evil. Being foolish and ignorant, ordinary people try to reap happiness by sowing suffering. For example, nowadays many people try to prolong their own lives by killing and eating all sorts of animals. Aren’t the means and the purpose completely contradictory to one another?

The Buddha once said that it is not so easy for an ordinary person to prove the existence of cause and effect, but not impossible. Buddhism holds the doctrine of dependent arising of all phenomena or compounded phenomena. What is dependent arising? It means that cause begets effect. All phenomena are the manifestations of dependent arising, the results of conditioned genesis. Suppose a person killed an animal. It caused great harm to that animal. How can there be no consequence for the person who had committed such grave karma? Like casually throwing a seed into the moist and warm soil, it will germinate on its own with no tending required. By the same token, in the phenomenal world, every cause must bear its own fruit with no exception.

On the other hand, virtue also has the possibility to turn into mutable karma. It is therefore important for us to save all virtuous karma as best we can. There are two ways to do that. One is dedication. The other, a better way, is to understand fully the meaning of emptiness, that is, knowing virtuous karma is, like dreams, intrinsically illusory. If we can contemplate in this way, even if anger arises, it cannot destroy the root of virtue. Because anger is defilement, a mental affliction rooted in attachment, it is incompatible with the view that all phenomena are illusory. But the virtuous actions we performed are directly associated with attaining realization of that view. Since something mired in attachment is inferior to the virtuous root planted with wisdom, anger cannot destroy this root of virtue. If we have neither attained any realization nor dedicated merit, but are constantly filled with anger, virtuous karma will be destroyed very easily. For ordinary people, the best way to save accumulated good karma is dedication of merit.
