Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 36
Sanskrit:
सोऽयं प्रतिहतो वज्रो मया मुक्तोऽसुरेऽल्पके ।नाहं तदाददे दण्डं ब्रह्मतेजोऽप्यकारणम् ॥ ३६ ॥
ITRANS:
so ’yaṁ pratihato vajromayā mukto ’sure ’lpakenāhaṁ tad ādade daṇḍaṁbrahma-tejo ’py akāraṇam
Translation:
But now, although the same thunderbolt has been released against a less important demon, it has been ineffectual. Therefore, although it was as good as a brahmāstra, it has now become useless like an ordinary rod. I shall therefore hold it no longer.
