Pure Sustenance of Food

While the Buddha is staying at the Bamboo Grove with a diverse retinue, the monk Maudgalyāyana asks him about some unusual beings he saw during an alms round. The Buddha informs Maudgalyāyana that these beings are starving spirits. The Buddha gives a discourse explaining how these starving spirits were once humans yet committed misdeeds related to food that led them to their current dismal state. The misdeeds connected with food described by the Buddha present a picture of food-related prohibitions for the monastic saṅgha, such as failing to eat only a single meal a day, improperly partaking of meals, carrying away leftovers, and other forms of abusing food offerings. Food-related ethics are also given for lay people, mainly concerning how to prepare food for the saṅgha in a hygienic manner.
