Bhīṣma said: One should not void urine or feces near a temple, among cows, at a sacred shrine (caitya), near trees connected with worship, near a resting place, or in flourishing cultivated fields. After eating, after sneezing, after traveling on the road, and after relieving oneself, one should perform the proper purification and then sip water twice in the prescribed manner (ācāmana)—drinking enough that it is felt to reach the heart. A man who is about to eat should perform ācāmana three times; after eating he should again do so three times, and then wipe the mouth twice with the base of the thumb.
भीष्म उवाच
Maintain śauca (purity) by respecting sacred and communal spaces—temples, shrines, cattle areas, resting places, and cultivated fields—and by performing prescribed ācāmana and cleansing after common impurity-causing acts such as eating, sneezing, traveling, and excretion.
In the Anuśāsana Parva’s instruction section, Bhīṣma continues advising on dharmic conduct, giving practical rules of daily purity: prohibitions about where to relieve oneself and the proper sequence and manner of ācāmana before and after meals and after other activities.
