Gaṅgā-māhātmya: Siddha–Śilavṛtti-saṃvāda and Gaṅgā-stava (गङ्गामाहात्म्यं—सिद्ध-शिलवृत्ति-संवादः)
यः प्रवृत्तां श्रुतिं सम्यक् शास्त्र वा मुनिभि: कृतम् । दूषयत्यनभिज्ञाय त॑ विद्याद् ब्रह्मघातिनम्
yaḥ pravṛttāṃ śrutiṃ samyak śāstraṃ vā munibhiḥ kṛtam | dūṣayaty anabhijñāya taṃ vidyād brahmaghātinam ||
Bhishma dijo: «Quien, sin verdadero entendimiento, denigra la śruti autorizada —la revelación védica que prescribe la acción correcta— o los śāstra compuestos por los sabios, debe ser tenido por un matador de Brahman, pues comete una grave ofensa espiritual al socavar los cimientos del dharma.»
भीष्म उवाच
Do not condemn Śruti or sage-authored Śāstra without proper understanding; such reckless disparagement is treated as a grave offense because it erodes the very sources that guide dharma and right conduct.
In Bhīṣma’s instruction on dharma (Anuśāsana Parva), he warns the listener that ignorant criticism of Vedic injunctions and authoritative teachings is spiritually dangerous and socially harmful, and he classifies the offender among the gravely sinful.
