1. (Nor shall he study) on the days of the full moons of those months in which the Kāturmasya-sacrifice may be performed (nor on the days preceding them). 2. At the time of the Vedotsarga, on the death of Gurus, at the Ashlakā-Śrāddha, and at the time of the Upākarma, (he shall not study) for three days; 3. Likewise if near relations have died. 4. (He shall not study) for twelve days, if his mother, father, or teacher have died. 5. If these (have died), he must (also) bathe for the same number of days. 6. Persons who are younger (than the relation deceased), must shave (their hair and beard), 7. Some declare, that students who have returned home on completion of their studentship, shall never shave, except if engaged in the initiation to a Śrauta-sacrifice. 8. Now a Brāhmaṇa also declares, 'Verily, an empty, uncovered (pot) is he, whose hair is shaved off entirely; the top-lock is his covering.' 9. But at sacrificial sessions the top-lock must be shaved off, because it is so enjoined in the Veda. 10. Some declare, that, upon the death of the teacher, (the reading should be interrupted) for three days and three nights. 11. If (he hears of) the death of a learned Brāhmaṇa (Śrotriya) before a full year (since the death) has elapsed, (he shall interrupt his reading) for one night (and day). 12. Some declare, (that the deceased Śrotriya must have been) a fellow-student. 13-14. If a learned Brāhmaṇa (Śrotriya) has arrived and he is desirous of studying or is actually studying, (or if he is desirous of teaching or is teaching,) he may study or teach after having received permission (to do so from the Śrotriya). 15-16. He may likewise study or teach in the presence of his teacher, if (the latter) has addressed him (saying), 'Ho, study! (or, Ho, teach!)' 17. When a student desires to study or has finished his lesson, he shall at both occasions embrace the feet of his teacher. 18. Or if, whilst they study, another person comes in, he shall continue his recitation, after those words, ('Ho, study!') have been pronounced (by the newcomer). 19. The barking of (many) dogs, the braying of (many) asses, the cry of a wolf or of a solitary jackal or of an owl, all sounds of musical instruments, of weeping, and of the Sāman melodies (are reasons for discontinuing the study of the Veda). 20. If another branch of the Veda (is being recited in the neighbourhood), the Sāman melodies shall not be studied.
