## Anuttaraupapatikadasha 18-32:
**18. Patan:** When a great king or national leader dies, one should not perform *svadhyaya* until their cremation is completed. Alternatively, one should gradually resume *svadhyaya* after the ten officials take charge.
**19. Rajavyudgraha:** When there is a war between nearby kings, one should not perform *svadhyaya* for one day and night, even after peace is restored.
**20. Audarik Sharira:** When a five-sense being dies within the *upaashraya*, one should not perform *svadhyaya* as long as the body remains there. If the lifeless body remains within a hundred *haath* (cubits), *svadhyaya* should be avoided.
The above ten reasons for avoiding *svadhyaya* are related to the *audarik sharira* (physical body).
**21-28. Four Mahotsav and Four Mahapratipada:** The four *mahotsav* (festivals) are Ashadh Purnima, Ashwin Purnima, Kartik Purnima, and Chaitra Purnima. The *pratipada* (first day) following these full moons are called *mahapratipada*. *Svadhyaya* is prohibited during these days.
**29-32. Pratah, Sayam, Madhyahna, and Ardharatri:** One should not perform *svadhyaya* one *ghadi* (hour) before and after sunrise, one *ghadi* before and after sunset, one *ghadi* before and after midday, and one *ghadi* before and after midnight.
