Shloka 8
Prajñā as Pratiṣṭhā — Indra–Kāśyapa Saṃvāda (Śānti-parva 12.173)
स्वाध्यायेन वियुक्तो हि ब्रह्म॒वर्चसवर्जित: । तद्व्र॒तस्तत्र मे शंका हन्यात् तं॑ स द्विजाधम:
svādhyāyena viyukto hi brahmavarcasa-varjitaḥ | tadvratas tatra me śaṅkā hanyāt taṃ sa dvijādhamaḥ ||
毗湿摩说：“因为他不修自习诵读（svādhyāya），又失却婆罗门的光辉威德。他的行状似乎正趋向那般恶途；故我疑他——唯恐那卑劣的婆罗门会杀害我的朋友。”

Educational Q&A
The verse links ethical reliability to disciplined learning: one who abandons svādhyāya and lacks brahmavarcasa (the moral-spiritual authority born of Vedic discipline) is portrayed as prone to harmful conduct, and thus becomes an object of justified caution.
Bhishma expresses apprehension about an unworthy Brahmin whose lack of Vedic study and spiritual radiance makes him seem violent; Bhishma fears that this person may harm (even kill) Bhishma’s friend.
