佛說觀佛三昧海經 6.6

6.6

佛告大眾：「三界眾生輪迴六趣，如旋火輪，或為父母、兄弟、宗親，三界一切無不是汝所親之者，云何起意生殺嫉心？」

The Buddha said to the great assembly: "Sentient beings of the three realms transmigrate through the six destinies like a whirling firebrand, becoming at times parents, brothers, and clan relatives. None in the three realms is not your close kin; how could you give rise to intentions of killing and jealousy?"
