Since there are various ideas of punishment in the Buddhist sects, it is difficult to explain the reason considering all ideas, but if we try to think of the reason, it is a general interpretation that the Buddha who has such a great capacity for mercy as Buddha and Nyorai including Shakyamuni buddha are said to proclaim that 'all living things are my children,' so those who are plenteous in mercy will not give punishment.
仏教宗派における罰の概念は様々であるため、そのすべてを網羅して説明するのは難しいが、あえてその理由を挙げると、釈迦仏をはじめとする仏如来は「一切衆生は皆我が子なり」と言われるように、そのような大いなる慈悲心を持つ仏が罰を与えることはない、というのが一般的な解釈である。
