SB 10.11.47
te tatra dadrsur bala
maha-sattvam avasthitam
tatrasur vajra-nirbhinnam
gireh srngam iva cyutam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Right by the reservoir, the boys saw a gigantic body resembling a mountain peak broken and struck down by a thunderbolt. They were afraid even to see such a huge living being.
