भूमिदान-प्रसङ्गः । काश्यपी-पृथिवी तथा उतथ्य-वरुण-संवादः
Land-gift episode; Pṛthivī Kāśyapī; Utathya–Varuṇa dispute
एक ओर रत्नोंसे भरी हुई सम्पूर्ण पृथ्वी प्राप्त होती हो और दूसरी ओर यह सर्वोत्तम ज्ञान मिल रहा हो तो उस पृथ्वीको छोड़कर इस सर्वोत्तम ज्ञानको ही श्रवण एवं ग्रहण करना चाहिये। धर्मज्ञ पुरुष ऐसा ही माने ।।
ekataḥ ratnaiḥ pūrṇā samastā pṛthivī prāpyeta, aparataḥ ca idaṃ śreṣṭhaṃ jñānaṃ labhyeta; tadā tāṃ pṛthivīṃ parityajya idaṃ śreṣṭhaṃ jñānam eva śrotavyaṃ grāhyaṃ ca. dharmajñaḥ puruṣaḥ evam eva manyeta. na aśraddadhānāya, na nāstikāya, na naṣṭa-dharmāya, na nirghṛṇāya; na hetu-duṣṭāya, guru-dviṣe vā, na anātma-bhūtāya—nivedyam etat.
ビーシュマは言った。「一方に宝玉で満ちた全地を得られ、他方にこの無上の知があるなら、その地を捨てて、この最上の知をこそ聞き、受け取るべきである。ダルマを知る者はそのように判断すべきだ。この教えは、信なき者、無神論者（ナースティカ）、ダルマを滅する者、残酷な者、詭弁を盾に悪をなす者、師（グル）を憎む者、身を我と執する者には授けてはならない。かかる者には秘して明かすべからず。」

Educational Q&A
Supreme knowledge (śreṣṭha-jñāna) is more valuable than even a jewel-filled earth; therefore one should prioritize hearing and assimilating it. Yet such instruction must be given only to qualified recipients—those with faith, moral integrity, compassion, respect for the teacher, and freedom from mere bodily self-identification.
In the Anuśāsana Parva, Bhīṣma continues his post-war instruction on dharma. Here he contrasts worldly sovereignty and wealth with the higher worth of liberating knowledge, and he sets boundaries on transmission: the teaching should not be disclosed to people who are faithless, atheistic, destructive of dharma, cruel, sophistical in wrongdoing, hostile to the guru, or entrenched in dehābhimāna (body-identification).
