Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Lord Nrsimhadeva’s mouth and mane were sprinkled with drops of blood, and His fierce eyes, full of anger, were impossible to look at. Licking the edge of His mouth with His tongue, the Supreme Personality of Godhead, Nrsimhadeva, decorated with a garland of intestines taken from Hiranyakasipu’s abdomen, resembled a lion that has just killed an elephant.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The hair on Lord Nrsimhadeva’s face, being sprinkled with drops of blood, was reddish and looked very beautiful. Lord Nrsimhadeva pierced Hiranyakasipu’s abdomen with His nails, pulled out the demon’s intestines and wore them as a garland, which enhanced His beauty. Thus the Lord became very fearsome, like a lion engaged in fighting an elephant.
