SB 1.7.21
tatah praduskrtam tejah
pracandam sarvato disam
pranapadam abhipreksya
visnum jisnur uvaca ha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thereupon a glaring light spread in all directions. It was so fierce that Arjuna thought his own life in danger, and so he began to address Lord Sri Krsna.
