毘羅三昧經云。佛為法慧菩薩說四食時。一旦時。為天食。二午時。為法食。時佛斷六趣因。令同三世佛故。制日午為法食。正時也○僧祇律云。午時日影過一髮一瞬。即是非時。

The Piluo sanmei jing says: The Buddha explained the four meal times to the Bodhisattva Dharmamati: First, the morning time is the meal for the devas. Second, the noon time is the meal of Dharma. At this time, the Buddha cuts off the causes of the six destinies and causes [beings] to be equal to the Buddhas of the three periods of time; therefore, he instituted noon as the Dharma meal, which is the proper time. / The Sengqi lü says: If the sun's shadow at noon passes by a hair or the blink of an eye, it is an improper time.
