There are two types of dedication: poisonous and nonpoisonous. “Poisonous dedication” means dedication with attachment. It is stated in the Prajnaparamita Sutra that good seeds sown with attachment is like poisonous food. It may taste delicious at first, but will cause tremendous pain when the poison takes effect. Similarly, good seeds sown not by actions performed with mind free of clinging, as explained above, may perhaps yield some transitory benefit, but more suffering will ensue and no liberation attained because such actions are deemed defiled phenomena.

Nonpoisonous dedication refers to dedication free of attachment and concepts, i.e. to dedicate while in the state of realization that the true nature of all phenomena is emptiness. Nonpoisonous dedication is further classified into two types—genuine and simulated. Genuine nonpoisonous dedication refers to the one made by the bodhisattvas, who have arrived at the first ground or higher, in a state of thought-free concentration. It is beyond the capability of ordinary people whose capacity is more suitable for simulated nonpoisonous dedication. This type of dedication is not to use the logic of Madhyamaka to discern the void nature of all phenomena but the visualization as described in the Thirty-five Buddhas Repentance Ritual . One should visualize in earnest as follows: “However the Buddhas and bodhisattvas of all times and ten directions dedicate their merit, I do the same with mine.” This way is simulated nonpoisonous dedication.

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.
