शिर:स्नातो<थ कुर्वीत दैवं पित्रमथापि च
śiraḥ-snātaḥ atha kurvīta daivaṁ pitṛm athāpi ca, bhārata!
ビーシュマは言った。「おおバーラタよ、頭を清めて沐浴したのち、神々のための儀礼を行い、また祖霊のための儀礼をも行うべきである。」（この儀礼規範においてさらに、シュラーダッハ（śrāddha）は自らの生誕ナクシャトラ、プールヴァバードラパダーとウッタラバードラパダーの両宿、そしてクリッティカーにおいて禁じられると述べられる。）

Educational Q&A
Ritual acts should be performed with proper purity and order: after a head-bath, one should carry out divine rites and ancestral rites. The broader instruction emphasizes that even meritorious acts like śrāddha are governed by rules of time (nakṣatra) and propriety.
In the Anuśāsana Parva, Bhīṣma instructs Yudhiṣṭhira on dharma, especially duties, observances, and ritual conduct. Here he gives a practical injunction about preparing through bathing and then performing daiva- and pitṛ-related rites, along with a note on certain nakṣatras where śrāddha is disallowed.
