Why we ordinary beings keep drifting in samsara is century-old question to which only the Buddha can fully answer. Others, even being adept in all the disciplines of the world, will still draw a blank when confronted with this question. The Buddha, with transcendent wisdom, gave the answer in a nutshell: It is not by accident or God’s will that one is born a human or an animal. There is always a cause. Such cause is the origin of suffering, and suffering itself is the effect of samsara.
