The belief in reincarnation is one of the fundamental moral laws. Because people have not been educated about this law of cause and effect, which continues to operate from one existence to another, one can tell them whatever one wants, and they will not change. In contrast, the one who knows that the difficulties and trials they face in the present existence are the result of misbehavior in past lives will not only accept these difficulties but will also choose to work for the good in order to improve their future reincarnations.
