Droṇa-parva Adhyāya 96: Sātyaki’s Line-Penetration, Encirclement, and Advance toward Arjuna
अड्विराः प्राह पुत्रस्य मन्त्रज्ञस्थ बृहस्पते: । बृहस्पतिरथोवाच आग्निवेश्याय धीमते,अंगिराने अपने मन्त्रज्ञ पुत्र बृहस्पतिको उसका उपदेश दिया और बृहस्पतिने परम बुद्धिमान् आग्निवेश्यको यह विद्या प्रदान की
aṅgirāḥ prāha putrasya mantrajñasya bṛhaspateḥ | bṛhaspatir athovāca āgniveśyāya dhīmate |
शर्व उवाच—अङ्गिराः पुत्रं मन्त्रज्ञं बृहस्पतिं प्राह। बृहस्पतिरथो धीमते आग्निवेश्याय तां विद्यां प्रददौ।
शर्व उवाच
The verse emphasizes the ethical and cultural ideal of preserving sacred knowledge through an authentic teacher–student lineage: a qualified teacher transmits, and a worthy, intelligent recipient receives and carries it forward.
Śarva recounts a succession of instruction: Aṅgiras teaches his son Bṛhaspati, and Bṛhaspati then teaches the sage Āgniveśya, establishing a chain of authoritative transmission.
