मातापितृगुरुपूजा-प्रशंसा
Praise of Venerating Mother, Father, and Teacher
यश्नचावृणोत्यवितथेन कर्मणा ऋतं ब्रुवन्ननृतं सम्प्रयच्छन् । त॑ं वै मन््येत पितरं मातरं च तस्मै न द्रहोत् कृतमस्य जानन्
yaś ca āvṛṇoty avitathena karmaṇā ṛtaṁ bruvan anṛtaṁ samprayacchan | taṁ vai manyeta pitaraṁ mātaraṁ ca tasmai na drohot kṛtam asya jānan ||
ビーシュマは言った。「揺るがぬ正しい行いによって（弟子を）鎧のごとく覆い護り、ṛta—ヴェーダの真なる秩序—を宣べ、虚偽を抑え止める者、その師は父であり母であると見なすべきである。彼から受けた恩益を知るなら、そのグルに対して決して背信してはならない。」
भीष्म उवाच
Educational Q&A
A true guru protects the student through impeccable conduct, teaches ṛta (truth/Vedic order), and restrains falsehood; therefore the guru deserves the reverence due to both parents, and one must never betray him, remembering his benefaction.
In the Śānti Parva’s instruction on dharma, Bhishma continues advising on ethical duties and proper relationships, here emphasizing the moral status of the guru and the obligation of gratitude and non-treachery toward one’s teacher.
