Buddha Sakyamuni in his time expounded the doctrine of cause and effect – all of the happiness and suffering in our everyday life arise not from the spirits or for no reason, but from two types of cause and condition.
The first type of cause and condition is called proximate condition (the causes and conditions which occurred recently); the other type is called distant condition (the causes and conditions which were produced at an earlier time in the past). When these two conditions converge, a result is produced. This is cause and effect.
