Anuśāsana-parva 108
दारुणेषु च सर्वेषु प्रत्यरें च विवर्जयेत् । ज्योतिषे यानि चोक्तानि तानि सर्वाणि वर्जयेत्
Bhīṣma uvāca: dāruṇeṣu ca sarveṣu pratyareṃ ca vivarjayet | jyotiṣe yāni cok tāni tāni sarvāṇi varjayet ||
毗湿摩说道：“一切凶厉之宿皆当回避，所谓‘普罗提亚里’（pratyari，敌对之星）亦当避之。总而言之，凡占星传统所判为不宜之宿，皆应尽避：在其下既不可行供天之礼，亦不可行祭祖之仪。”

Educational Q&A
Ritual acts—especially offerings to gods and ancestors—should be performed with attention to auspicious timing; nakṣatras deemed inauspicious or hostile in jyotiṣa are to be avoided for such rites.
In Bhishma’s instruction on dharma and ritual propriety, he advises the listener to refrain from conducting devakārya and pitṛkārya during nakṣatras classified as dāruṇa or pratyari, summarizing this as adherence to astrological prohibitions.
