सूचका: सेतुभेत्तार: परवृत््युपजीवका: । अकृच्ञाश्च मित्राणां ते वै निरयगामिन:
bhīṣma uvāca | sūcakāḥ setubhettāraḥ paravṛttyupajīvakāḥ | akṛjñāś ca mitrāṇāṃ te vai nirayagāminaḥ ||
सूचकाः सेतुभेत्तारः परवृत्त्युपजीवकाः । अकृतज्ञाश्च मित्राणां ते वै निरयगामिनः ॥
भीष्म उवाच
Bhishma teaches that betrayal through informing/tale-bearing, breaking dharmic and social boundaries, exploiting others’ livelihoods, and ingratitude toward friends are serious moral offenses that lead to grave karmic consequences (symbolized as going to niraya/hell).
In Anushasana Parva, Bhishma is instructing Yudhishthira on dharma and proper conduct. Here he lists specific harmful character-types—informers, boundary-breakers, exploiters, and the ungrateful—and states their dire fate to warn against such behavior.
