Listen with reverence to the sacred guidance offered in these verses. The wise instruct that one should never revile yogis, Brahmins, those who observe vows, or ascetics; such beings are to be honored, not disparaged. On the days of the new moon and the full moon, it is prescribed that one should perform the appropriate sacrifices, as these are moments of spiritual significance. If a person neglects worship, the sages declare him to be no better than a drinker of liquor, for he has abandoned what is sacred. For the twice-born householder, the śrāddha rites must be performed on the new moon and during the fortnight dedicated to the ancestors. Yet, these rites should not be conducted when grain is unavailable, for the offering must be proper and complete. The householder is further advised to perform śrāddha in holy places and at sacred fords, where the spiritual atmosphere is most auspicious. It is said that any act performed without the crown-shaped mark is in vain; fruitless conduct must be abandoned, and those who seek welfare among the twice-born should avoid such actions. The twice-born are enjoined to properly perform those deeds which yield the fruits of all actions. When Lord Viṣṇu is pleased, nothing is impossible, O best of the twice-born. When these rites are performed, all sins are destroyed without doubt. A brāhmaṇa, after arranging his hair, should consider his means of livelihood. When relieving himself of urine and feces at night, he should face south. While carrying wood in one hand, the twice-born must maintain silence, and this same restraint is to be observed in the shade of a tree, in the wilderness, near fire, near brāhmaṇas, cows, enclosures, or women. In such places, one must not pass urine or feces. For one lacking purity of conduct, all actions are fruitless. External purity is achieved with clay and water, while internal purity is attained through one's disposition. Clay dug up by mice or similar creatures, or clay of superior quality, should not be used; instead, one must carefully select auspicious clay for purification. The wise declare this as the purification after urination and defecation. Three lumps of clay should be given separately for the feet; this is the purification for a householder, while a student requires twice as much. In one’s own place, complete cleanliness should be maintained, and on the path, half that amount suffices, O best of sages. A discerning person should cleanse himself to remove odors and dirt. For all those observing vows, purity like that of ascetics is prescribed. Having thus performed purification, one should, with full concentration, drink water three or four times, ensuring it is free from smell, foam, and other impurities. With thumb and forefinger joined, one should touch both nostrils; with thumb and little finger joined, the twice-born should touch the navel region. Using the palm or fingertips, the wise are to touch their shoulders. Then, one should chew a tooth-stick, with bark, taken from a proper tree. After washing it with water or consecrating it with a mantra, one should pray, “O tree, grant me Brahman, wisdom, and intelligence from yourself.” For a Kshatriya, the tooth-stick should be nine finger-breadths in length; for a Vaishya, eight finger-breadths. If proper tooth-sticks are unavailable, one should use mouthfuls of water equal to the measure of the sun. Taking the stick in the left hand, one should rub with the left canine tooth. After scraping the tongue with these two, one who has controlled the senses should then bathe at the beginning of a river or in pure water. Thus, the sacred duties are laid out, guiding the twice-born and all seekers on the path of purity and righteousness.
