tam syena-vegam sata-candra-vartmabhis
carantam acchidram upary-adho harih
krtvatta-hasam kharam utsvanolbanam
nimilitaksam jagrhe maha-javah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Making a loud, shrill sound of laughter, the Supreme Personality of Godhead, Narayana, who is extremely strong and powerful, captured Hiranyakasipu, who was protecting himself with his sword and shield, leaving no gaps open. With the speed of a hawk, Hiranyakasipu moved sometimes in the sky and sometimes on the earth, his eyes closed because of fear of Nrsimhadeva’s laughter.
