Shloka 8
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 ||
毗湿摩说道：“凡是不明其义而妄加诋毁权威的‘闻传（śruti）’——即规定正当行为的吠陀启示——或贬斥诸圣贤所作的论典（śāstra）者，当视为‘杀梵’之人；因其动摇达摩之根基，犯下极重的灵罪。”

Educational Q&A
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.
