Tīrtha-vaṃśa Upadeśa: Instruction on the Fruits of Sacred Waters
गुर्वर्थमभयार्थ वा वर्जयित्वा युधिष्ठिर । येडनृतं कथयन्ति सम ते वै निरयगामिन:
gurvartham abhayārthaṃ vā varjayitvā yudhiṣṭhira | ye 'nṛtaṃ kathayanti samā te vai nirayagāminaḥ ||
ビーシュマは言った。「ユディシュティラよ、師の利益のため、あるいは他者を恐怖から解き放つために不実を語る場合を除き、他の場で虚言を吐く者は、まことに地獄へ赴く定めである。」
भीष्म उवाच
Truthfulness is the norm in dharma, and falsehood generally leads to grave moral consequence; however, Bhīṣma acknowledges narrow exceptions—speaking untruth to benefit the guru or to protect someone from fear—while condemning other lies as hell-leading.
In the Anuśāsana Parva, Bhīṣma instructs Yudhiṣṭhira on righteous conduct. Here he addresses the ethics of speech, distinguishing rare protective or duty-based exceptions from ordinary deceit, and warns of the karmic result of habitual or self-serving lying.
