Droṇa-parva Adhyāya 96: Sātyaki’s Line-Penetration, Encirclement, and Advance toward Arjuna
त्वष्टा पुरा तपस्तप्त्वा वर्षायुतशतं तदा । वृत्रो विनिर्मितो देवा: प्राप्यानुज्ञां महेश्वरात्,“देवगण! प्राचीन कालमें त्वष्टा प्रजापतिने दस लाख वर्षोतक तपस्या करके भगवान् शंकरसे वरदान पाकर वृत्रासुरको उत्पन्न किया था

tvaṣṭā purā tapastaptvā varṣāyutaśataṁ tadā |
vṛtro vinirmito devāḥ prāpyānujñāṁ maheśvarāt ||
ସଞ୍ଜୟ କହିଲେ—ପୁରାତନ କାଳରେ ତ୍ୱଷ୍ଟା ଲକ୍ଷଲକ୍ଷ ବର୍ଷ ଘୋର ତପ କରିଥିଲେ। ପରେ ମହେଶ୍ୱର (ଶିବ)ଙ୍କ ଅନୁମତି ପାଇ ବୃତ୍ରକୁ ନିର୍ମାଣ କଲେ।

Extraordinary power gained through tapas is not value-neutral: its use requires restraint and right intention, and even then it operates within a moral universe where actions can unleash far-reaching consequences; divine permission underscores accountability rather than license.
Sañjaya cites an ancient precedent: Tvaṣṭṛ, after immense austerities, receives Śiva’s consent and creates Vṛtra. The episode functions as a mythic illustration within the war narrative, invoking a well-known cosmic conflict to illuminate the gravity of the present events.
