आपद्धर्मे वैश्यवृत्तिः, विक्रय-निषेधाः, तथा ब्रह्म-क्षत्र-सम्बन्धः
Emergency Livelihood, Prohibited Trade, and Brahman–Kshatra Regulation
ब्राह्मणस्त्रिषु कालेषु शस्त्र गृह्नन्न दुष्पति । आत्मत्राणे वर्णदोषे दुर्दम्यनियमेषु च,अपनी रक्षाके लिये, अन्य वर्णो्में यदि कोई बुराई आ रही हो तो उसे रोकनेके लिये तथा दुर्दान्त दुष्टोंका दमन करनेके लिये--इन तीन अवसरों पर ब्राह्मण भी शस्त्र ग्रहण करे तो उसे दोष नहीं लगता

भीष्म उवाच—ब्राह्मणः त्रिषु कालेषु शस्त्रं गृहीत्वा न दोषं प्राप्नोति—आत्मत्राणे, वर्णदोषनिवारणे, दुर्दम्यदुष्टनिग्रहे च।
भीष्म उवाच
Non-violence and restraint are normative for a Brahmin, but dharma allows exceptional recourse to weapons when the aim is protection: safeguarding oneself, preventing breakdown of the social-moral order, and restraining dangerous wrongdoers. The intent (protection and restoration of order) is central to whether the act is blameworthy.
In the Shanti Parva’s instruction on dharma and governance, Bhishma advises Yudhishthira about when force is justified. Here he clarifies that even a Brahmin may take up arms in three specific emergencies tied to protection and the maintenance of order.
