SB 4.5.23
sastrair astranvitair evam
anirbhinna-tvacam harah
vismayam param apanno
dadhyau pasupatis ciram
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
He tried to cut the head of Daksa with hymns as well as weapons, but still it was hard to cut even the surface of the skin of Daksa’s head. Thus Virabhadra was exceedingly bewildered.
