नैते देवैर्न पितृभिर्न गन्धर्वर्न राक्षसै: । नासुरैर्न पिशाचैश्न शक्या जेतुं द्विजातय:,ये द्विज न तो देवताओं, न पितरों, न गन्धर्वों, न राक्षसों, न असुरों और न पिशाचोंद्वारा ही जीते जा सकते हैं
naite devair na pitṛbhir na gandharvair na rākṣasaiḥ | nāsurair na piśācaiś ca śakyā jetuṃ dvijātayaḥ ||
Bhishma said: These twice-born men cannot be conquered—not by the gods, nor by the ancestors, nor by the Gandharvas, nor by the Rākṣasas, nor by the Asuras, nor even by the Piśācas.

The verse asserts the invincibility—especially in a dharmic and moral sense—of the dvijātis who are established in Vedic conduct, restraint, and righteous living; even powerful supernatural classes are said to be unable to subdue such disciplined righteousness.
In Anuśāsana Parva, Bhīṣma continues his instruction on dharma and proper conduct. Here he emphasizes the exceptional standing of the twice-born within the moral order, describing them as unconquerable by various divine and demonic beings.
