महाभारतः mahābhārataḥ - book-1, chapter-171, verse-2

वृथारोषप्रतिज्ञो हि नाहं जीवितुमुत्सहे ।
अनिस्तीर्णो हि मां रोषो दहेदग्निरिवारणिम् ॥२॥

2. vṛthāroṣapratijño hi nāhaṁ jīvitumutsahe ,
anistīrṇo hi māṁ roṣo dahedagnirivāraṇim.

2. vṛthā-roṣa-pratijñaḥ hi na aham jīvitum utsahe
aniṣṭīrṇaḥ hi mām roṣaḥ dahet agniḥ iva araṇim

2. Indeed, I would not wish to live if my vow (pratijñā), made from anger (krodha) in vain, were to become fruitless. For unfulfilled anger (roṣa) would surely consume me, just as fire consumes the kindling stick (araṇi).
