法苑珠林 11.25

11.25

又菩薩處胎經云。佛告苦行菩薩。昔我所更苦行無數。於尼連河邊六年苦行。日食一麻一米。斯由曩昔向一緣覺犯口四過斷絕一施。重受輕報。

The Pusa chutai jing also states: The Buddha told the ascetic Bodhisattva: "Formerly, the austerities I underwent were countless. For six years of austerities on the banks of the Nairañjanā River, eating a single sesame seed and a single grain of rice a day, this was because in the distant past I committed four verbal faults against a pratyekabuddha and severed an offering; thus a heavy retribution was received lightly."
