佛說自愛經 1.25

1.25

佛告王曰：「昔彼王飯佛，王心念言：『佛如國王，沙門猶臣下。』王種斯栽，今自獲其果。彼一人云：『佛若牛，弟子如車。』彼自種車轢之栽，今在太山為火車所轢，自獲其果也。非王勇健所能致矣！為善福隨，履惡禍追，響之應聲，善惡如音，非天、龍、鬼、神所為，非先靈所為，造之者心、成身口矣！」

The Buddha told the king: 'In the past, when that king fed the Buddha, you thought in your heart: "The Buddha is like a king, and the śramaṇas are like ministers." You planted this seed, and today you have naturally reaped its fruit. That other person said: "The Buddha is like an ox, and the disciples are like a cart." He planted the seed of being run over by a cart, and now in Mt. Tai he is run over by fiery carts, naturally reaping his fruit. This is not something your valor could have brought about! For doing good, blessings follow; for walking in evil, calamity pursues—just as an echo responds to a sound, good and evil follow like tones. It is not done by gods, dragons, ghosts, or spirits, nor is it done by ancestral spirits; that which creates it is the mind, completed through body and mouth!'
