SB 1.7.29
suta uvaca
srutva bhagavata proktam
phalgunah para-vira-ha
sprstvapas tam parikramya
brahmam brahmastram sandadhe
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Suta Gosvami said: Hearing this from the Personality of Godhead, Arjuna touched water for purification, and after circumambulating Lord Sri Krsna, he cast his brahmastra weapon to counteract the other one.
