The Supreme Buddha saw the endless journey of birth and death of all beings. It is remarkable how insightful the way he taught us about the reincarnation. He saw the way we are trapped within this journey without even knowing it. He described about this situation in his whole life, so that we can get at least some idea about how dangerous this journey is. Buddha taught us that if there is someone who is born in this world today, then that person should have been born somewhere prior to this life. If he could not realize Dhamma in this life, then he will definitely be born somewhere again. This is a brief introduction on the truth that the Gautama Buddha realized about the birth and the death.
