Lord Nṛsiṁhadeva’s fierce appearance was certainly most dangerous for the nondevotees, but for Prahlāda Mahārāja such a fearful appearance was not at all disturbing. The lion is very fearsome for other animals, but its cubs are not at all afraid of the lion. The water of the sea is certainly dreadful for all living entities on the land, but within the sea even the small fish is unafraid. Why? Because the small fish has taken shelter of the big ocean. It is said that although great elephants are taken away by the flooding waters of the river, the small fish swim opposite the current. Therefore although the Lord sometimes assumes a fierce appearance to kill the duṣkṛtīs, the devotees worship Him. Keśava dhṛta-nara-hari-rūpa jaya jagadīśa hare. The devotee always takes pleasure in worshiping the Lord and glorifying the Lord in any form, either pleasing or fierce.
