If one diminishes (one’s food daily by) one mouthful during the dark (half of the month) and increases (it in the same manner) during the bright half, and bathes (daily) at the time of three libations (morning, noon, and evening), that is called a lunar penance (Kandrayana).
Let him follow throughout the same rule at the (Kandrayana, called) yavamadhyama (shaped like a barley-corn), (but) let him (in that case) begin the lunar penance, (with a) controlled (mind), on the first day of the bright half (of the month).
He who performs the lunar penance of ascetics, shall eat (during a month) daily at midday eight mouthfuls, controlling himself and consuming sacrificial food (only).
If a Brahmana, with concentrated mind, eats (during a month daily) four mouthfuls in a morning and four after sunset, (that is) called the lunar penance of children.
He who, concentrating his mind, eats during a month in any way thrice eighty mouthfuls of sacrificial food, dwells (after death) in the world of the moon.
