Āśrama-dharma: Duties of the Four Life-Stages (आश्रमधर्मः)
तानि यः सम्प्रजानाति ज्ञाननिश्चयनिश्षित: । द्विजाति: श्रद्धयोपेत: स यह्टूं पुरुषो5रहति
tāni yaḥ samprajānāti jñānaniścayaniṣṣitaḥ | dvijātiḥ śraddhayopetaḥ sa yaṣṭuṃ puruṣo 'rhati ||
ビーシュマは言った。「それらの事柄を明らかに知り、定まった知によって確信を研ぎ澄まし、しかも信（śraddhā）を具えた二度生まれ（dvija）である者——その人こそ、祭祀を行うにふさわしい。」

Educational Q&A
Ritual action (yajña) should be undertaken by one who has clear understanding and firm knowledge, and who possesses śraddhā; worthiness is tied to inner qualification—discernment and faith—rather than mere external performance.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and right conduct. Here he specifies the qualifications of a person who may properly perform sacrifice, emphasizing knowledge-based certainty and sincere faith as prerequisites.
