After taking food, a person should find a clean and pure place to sit and, as a matter of discipline, rinse the mouth twice. Once the meal is finished, and after touching the lips and the inside of the mouth, one should put on fresh garments before resuming any study or sacred recitation. If, after eating, one spits, coughs, or breathes heavily, it is proper to rinse the mouth again before beginning study. Moreover, at both dawn and dusk—the sacred twilights—even if one has already rinsed, it is best to rinse once more. This act of cleansing is not limited to mealtimes or study. If one sheds tears, or if blood is drawn, rinsing the mouth is required anew. Even after rinsing, if one falls asleep, whether briefly or deeply, it is necessary to rinse again, perhaps even multiple times, depending on the situation. There are other occasions as well that call for this practice. Whenever a person touches a woman, touches their own body, or puts on a lower garment, rinsing is again appropriate. The same applies after touching one’s own hair or wearing clothes that have not been freshly washed. Those who desire true cleanliness should always rinse their mouths while seated, facing either east or north, for these directions are considered auspicious. Yet, rinsing alone is not enough if the feet remain unwashed; purity is incomplete without cleansing the feet. The act of rinsing should not be performed with rainwater, nor while standing, nor with water that has been drawn up in an improper manner. One should not rinse while sitting on sandals or a seat, nor with the knees sticking out, nor in any other improper posture. The water used should be pure—not foamy or defiled, nor water that has been looked upon by others. Rinsing should be done quietly, without making noise with the fingers, and with a focused mind, not one that is distracted. The hands should be steady, and the act should be performed within a proper enclosure, not outside it. Furthermore, water that has been sipped or even touched by Vaiśyas, women, or Śūdras should not be used for rinsing. When offering water to the ancestors, the water that passes between the thumb and forefinger is considered the highest and most appropriate. For the gods, water at the tips of the fingers is called ‘divine’ and is also recognized as ‘āṛṣa,’ belonging to the seers. Knowing these distinctions, one remains unconfused; this practice itself is the true sacred place for purification. O twice-born, whether impurity arises from the body, from fate, or from ancestral causes, one should cleanse and touch the mouth with the base of the thumb. With the index finger and thumb joined, both sides of the nose should be touched. Alternatively, one may touch the head with the thumb or both sides of the head. In these acts, it is taught that Brahma, Vishnu, and Mahesha become present. When both eyes are touched, the Moon and the Sun are pleased; when both ears are touched, the Wind and Fire are pleased. By touching the crown of the head, the person finds contentment and singular satisfaction. However, if the tongue touches the teeth or anything attached to the teeth, impurity results. Objects placed on the ground are to be regarded as one with the earth itself, and should not be used without proper intent and care. Yet, Manu declares that there is no fault in consuming fruits, roots, or sugarcane, even if they have touched the ground. In such cases, one should place the item on the ground, sip water, and sprinkle it, performing this act mindfully. The same applies for cloth or similar items—after touching them, one should sip water to ensure purity. After passing urine or feces, the hand used for holding objects does not become defiled. During the daytime, one should relieve oneself, but if it must be done at night, one should face south. It is proper to cover the head while evacuating stool or urine, showing modesty and respect. Acts of purification should never be performed in the presence of fire, in a cremation ground, or in places soiled by urine or feces. Nor should they be done while standing, in a place lacking shelter, or atop a mountain summit. One should not purify oneself among living beings, in pits, or while walking. Fields, marshes, sacred fords, and crossroads are also improper places for such acts. Thus, by observing these practices with care and reverence, one maintains bodily and spiritual purity, honoring the sacred order in all aspects of daily life.
