Kārttikeya
पवित्राणां पवित्र च यत् तद् ब्रूहि पितर्मम । एतच्छुत्वा तु वचन व्यास: परमधर्मवित् पुत्रायाकथयत् सर्व तत्त्वेन भरतर्षभ
pavitrāṇāṁ pavitraṁ ca yat tad brūhi pitar mama | etac chrutvā tu vacanaṁ vyāsaḥ paramadharmavit putrāyākathayat sarvaṁ tattvena bharatarṣabha ||
毗湿摩说道：“父亲啊，请告诉我：在一切能净化之物中，何者最为清净？请将这一切为我详述。”噢，婆罗多族之雄！毗耶娑——通达至上法（dharma）者——听到儿子的话，便如实而周全地为他开示一切。

Educational Q&A
The verse establishes the ethical-spiritual problem: among all means of purification, there is a supreme purifier. It emphasizes sincere inquiry and the role of a qualified teacher (Vyasa, 'knower of highest dharma') who responds with a complete and truthful explanation (tattvena).
A son (Shuka) asks his father (Vyasa) to identify and explain the most purifying principle or practice. The narrator addresses the listener as 'bharatarṣabha' and reports that Vyasa, renowned for dharma-knowledge, proceeds to teach his son in full detail.
