prayena me ’yam harinorumayina
vadhah smrto ’nena samudyatena kim
evam bruvams tv abhyapatad gadayudho
nadan nrsimham prati daitya-kuñjarah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Hiranyakasipu murmured to himself, “Lord Visnu, who possesses great mystic power, has made this plan to kill me, but what is the use of such an attempt? Who can fight with me?” Thinking like this and taking up his club, Hiranyakasipu attacked the Lord like an elephant.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In the jungle there are sometimes fights between lions and elephants. Here the Lord appeared like a lion, and Hiranyakasipu, unafraid of the Lord, attacked Him like an elephant. Generally the elephant is defeated by the lion, and therefore the comparison in this verse is appropriate.
