In ancient times, the wise sages laid down sacred guidelines for the study and practice of the Veda, ensuring that its recitation and contemplation were always approached with the utmost reverence and purity. They taught that when lightning flashes in the sky, study at night is forbidden, just as it is during the day; such times are not auspicious for engaging with sacred knowledge. Those who earnestly seek righteousness and merit must avoid study wherever foul odors are present, for purity of environment is essential. Study is also prohibited in moments of weeping, or when people are gathered together, for these are not times of calm and focus. One should not even let the thought of study arise in the mind when impure, after eating, or after consuming food that has been offered to the ancestors. If impurity arises due to events such as the death of a king, the eclipse by Rāhu, or a birth in the family, the Veda must not be recited for three days. As long as any impurity remains in the body of a learned Brāhmaṇa, the recitation of the Veda is to be avoided. After eating meat or food from a household in mourning, study must not be undertaken. Certain days are also set aside as unsuitable for study: the new moon, the fourteenth day of the lunar fortnight, the full moon, and the eighth day. The aṣṭakā days, both day and night, and the nights at the end of the seasons are also forbidden for study. The wise have declared that three aṣṭakā days occur in the dark fortnight. There are places, too, that are not fit for study: never should one undertake Vedic recitation under the kovidāra or kapittha trees. When a teacher has passed away, three nights of impurity are to be observed, during which study is suspended. It is said that at such times, harmful forces may be present, so one must be cautious and refrain from study. Yet, the sages also allowed for exceptions. At the beginning of study, at the conclusion of rituals, and during the recitation of sacrificial mantras, study is permitted. On aṣṭakā days and even when the wind blows fiercely, study may still be performed. Moreover, other Dharmaśāstras do not prescribe these restrictions on festival days. All these rules were once declared by Brahmā himself to the sages of pure mind. Those who are confused and stray outside the Veda should not be engaged in conversation by the twice-born. One who merely recites the words, without understanding, sinks like a cow in the mud; even if he knows the meaning, if he behaves like a Śūdra, he does not attain the true fitness to be a vessel of knowledge. A disciplined student should serve his teacher faithfully until the end of his bodily life. He should always study with constancy, steadfast in Brahman and composed in mind. He should practice continually, keeping discipline and devotion, and bathing with sacred ashes. This is what the divine Svāyambhuva Manu spoke in ancient days: through such discipline and purity, one attains the supreme, auspicious, and flawless state. When the study is complete and the meaning is understood, the best among the twice-born should then bathe. Having performed his vows, with a disciplined and capable self, he is ready for this sacred bath. He should carry two sacred threads, pure water, and a water-pot, and adorn himself with golden earrings. His Veda should be at hand, his hair and nails neatly cut, and his whole being purified. Except for gold, a Brāhmaṇa should wear a garland that is not red. He should avoid old or dirty clothes if he has the means, and not use shoes, garlands, or sandals during this time. He should not drape a garment over his left shoulder, nor wear deformed or defective clothing, but only those that are proper and free from faults. A Brāhmaṇa should take a wife who is endowed with good conduct and purity. He must always diligently avoid what is forbidden, remaining celibate as on the days of the threefold birth-rites. The initiated householder should observe all vows and purificatory practices faithfully, for neglecting these leads quickly to terrifying hells. Finally, he should perform the sacred household rites and the worship at twilight, thus upholding the ancient path and ensuring the blessings of the divine.
