Gaṅgā-māhātmya: Siddha–Śilavṛtti-saṃvāda and Gaṅgā-stava (गङ्गामाहात्म्यं—सिद्ध-शिलवृत्ति-संवादः)
अधर्मनिरतो मूढो मिथ्या यो वै द्विजातिषु । दद्यान्मर्मातिगं शोकं त॑ विद्याद् ब्रद्मघातिनम्
adharmanirato mūḍho mithyā yo vai dvijātiṣu | dadyān marmātigaṃ śokaṃ taṃ vidyād brahmaghātinam ||
Bhīṣma dit : «L’homme égaré, voué à l’adharma, qui ment et calomnie parmi les dvija (les “deux-fois-nés”)—s’il inflige un chagrin qui transperce jusqu’au vif, sachez qu’il est un tueur de brāhmaṇa (brahma-ghātin).»
भीष्म उवाच
False and malicious speech directed at the twice-born—especially speech that causes deep, piercing anguish—is treated as a grave moral offense, comparable in severity to brahmahatyā (the sin of killing a brāhmaṇa).
In Anuśāsana Parva, Bhīṣma continues his instruction on dharma, emphasizing ethical restraint in conduct and speech; here he warns that slander and harmful falsehood toward the dvijas brings extreme culpability.
