## Anadhyaya Kaal
**But the thunder and lightning should not be considered as Anadhyaya during Chaturmas. Because thunder and lightning are often due to the nature of the season. Therefore, from Ardra to Swati Nakshatra, it is not considered Anadhyaya.**
**5. Nirghat - When there is a loud thunder in the sky without clouds, or when there is a clap of thunder in the sky with clouds, it is Anadhyaya for two Praharas.**
**6. Yupaka - The evening of Pratipada, Dwitiya, and Tritiya in the Shukla Paksha, when the moonlight is visible, is called Yupaka. During these days, one should not study from Prahara to night.**
**7. Yakshadeepta - Sometimes, a light appears in a direction, like lightning, which appears in intervals. This is called Yakshadeepta. Therefore, one should not study as long as the Yaksha-like light is visible in the sky.**
**8. Dhumika - The time from Krishna-Kartik to Magh is the womb month of the clouds. During this time, a fine, water-like mist of smoky color falls. This is called Dhumika-Krishna. One should not study as long as this mist falls.**
**9. Mihika Shweta - In winter, a fine, water-like mist of white color is called Mihika. One should not study as long as this falls.**
**10. Raj-Udghāt - Due to the wind, dust spreads all over the sky. One should not study as long as this dust remains spread.**
**The above ten reasons are related to the sky. The following ten Anadhyayas are related to the generous.**
**11-12-13. Bone, Flesh, and Blood - If the bone, flesh, and blood of a five-sense Tiryanch are visible, it is Anadhyaya until those things are removed from there. The commentator considers it Anadhyaya if these things are present within 60 hands around.**
**Similarly, Anadhyaya is considered for the bone, flesh, and blood of a human being. The difference is that their Anadhyaya is for 100 hands and one day and night. The Anadhyaya for a woman's menstrual period is for three days. The Anadhyaya for a boy and a girl is considered for seven and eight days respectively.**
**14. Ashuchi - It is Anadhyaya until the excrement and urine are visible.**
