How many grains of rice did the Buddha eat daily during his extreme asceticism?

During his extreme asceticism, the Buddha is traditionally said to have eaten one grain of rice daily. This describes Siddhartha Gautama before enlightenment, when he was testing severe forms of self-mortification in search of liberation.

Accounts of his austerities describe a progressive reduction in food. Some versions mention one bean, one sesame seed or one grain of rice per day; other descriptions emphasize that he eventually consumed almost nothing. The purpose was not health or fasting as a modern practice, but the belief that weakening the body could free the mind from worldly attachment.

The result was catastrophic physical emaciation. Buddhist texts describe his ribs, veins and bones becoming clearly visible, while the effort still failed to produce awakening. Gautama eventually recognized that self-mortification was no more effective than luxury and adopted the Middle Way.

This episode is often confused with the Buddha’s later monastic routine, in which monks traditionally ate alms food, commonly one meal before noon. The single grain belongs specifically to the pre-enlightenment ascetic period, not to his life as a teacher.
