## Translation:
**Meaning:** Ten types of *asvadhyaya* (unsuitable time for study) are described due to reasons related to the sky. For example, a meteor shower (falling star): if a large meteor shower occurs, one should not study scriptures for one *prahar* (3 hours) [1]. One should not study scriptures as long as the direction appears red [2]. Similarly, one should understand the following: for two *prahar* when thunder roars [3], for one *prahar* when lightning flashes [4], for two *prahar* when it thunders [5], that is, when there is a loud roar in the sky, whether there are clouds or not, for three days during the *shukla paksha* (bright fortnight) and for three days when the moon is a crescent [6]. As long as a *yaksha* (a celestial being) appears in the sky [7], when there is white smoke [8], when there is black smoke [9], and when there is fog in months like *Magh* (January-February), one should not study scriptures, especially when it is raining [10]. When these reasons are present, one should not study scriptures. However, *asvadhyaya* due to thunder and lightning should not be considered during *chaturmasya* (four months of the rainy season), because thunder and lightning are common during this season. Therefore, *asvadhyaya* is not considered until *Ardra* and *Swati* nakshatras (lunar mansions).
Ten types of *asvadhyaya* also occur due to reasons related to the *oudarik* body (physical body). For example, when a bone is visible [1], when there is flesh nearby [2], when there is blood nearby [3], when there is impurity (excrement, urine, etc.) nearby [4], when one is near a cremation ground [5], during a lunar eclipse for 8, 12, or 16 *prahar* [6], during a solar eclipse for 8, 12, or 16 *prahar* [7], when a great king or other official dies - until their funeral rites are completed or until the new official takes charge, one should study slowly [8], at the battlefield of kings [9], when a five-sense being is killed within the shelter - for example, if someone has killed a pigeon or a rat, and when a human corpse or other corpse is lying within 100 *hasta* (cubits) [10].
One should also not study scriptures during the four great *pratipada* (first day of the lunar month): *Ashadha* *shukla* full moon and *Shravana* *pratipada* [2], *Ashwin* *shukla* full moon and *Kartik* *pratipada* [4], *Kartik* *shukla* full moon and *Margashirsha* *pratipada* [6], *Chaitra* *shukla* full moon and *Vaishakha* *pratipada* [8]. And one hour before sunrise and one hour after sunrise, and one hour before sunset.
