Srimad Bhagavatam Canto 08, Chapter 11, Text 36

SB 8.11.36

so ’yam pratihato vajro
 maya mukto ’sure ’lpake
naham tad adade dandam
 brahma-tejo ’py akaranam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
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 brahmastra, it has now become useless like an ordinary rod. I shall therefore hold it no longer.
