Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 5-6
Sanskrit:
एकां जग्राह बलवान् सा चुक्रोश भयातुरा ।तस्यास्तु क्रन्दितं श्रुत्वा पृषध्रोऽनुससार ह ॥ ५ ॥खड्गमादाय तरसा प्रलीनोडुगणे निशि ।अजानन्नच्छिनोद् बभ्रो: शिर: शार्दूलशङ्कया ॥ ६ ॥
ITRANS:
ekāṁ jagrāha balavānsā cukrośa bhayāturātasyās tu kranditaṁ śrutvāpṛṣadhro ’nusasāra ha
Translation:
When the very strong tiger seized the cow, the cow screamed in distress and fear, and Pṛṣadhra, hearing the screaming, immediately followed the sound. He took up his sword, but because the stars were covered by clouds, he mistook the cow for the tiger and mistakenly cut off the cows’ head with great force.
