tāni yaḥ samprajānāti jñānaniścayaniṣṣitaḥ | dvijātiḥ śraddhayopetaḥ sa yaṣṭuṃ puruṣo 'rhati ||
毗湿摩说：凡能明了这些事理，因定慧而使信念锋利坚固，并且为具信（śraddhā）的二生者（dvija）者——此人方堪行祭。

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.
