A month-long observance in which one begins by eating fourteen mouthfuls of food and decreases food intake by one mouthful every day until the new moon day, during which one does not eat anything at all. Then, during the moon’s waxing phase, one increases food intake by one mouthful a day until the full moon.

An ascetic observance in which one’s food intake decreases and increases based on the waning and waxing phases of the moon.
