vayam kimpurusas tvam tu
ayam kupuruso nasto
dhik-krtah sadhubhir yada
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The inhabitants of Kimpurusa-loka said: We are insignificant living entities, and You are the Supreme Personality of Godhead, the supreme controller. Therefore how can we offer suitable prayers unto You? When this demon was condemned by devotees because they were disgusted with him, he was then killed by You.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The cause of the Supreme Lord’s appearance upon this earth is stated in Bhagavad-gita (4.7-8) by the Lord Himself:
yada yada hi dharmasya
glanir bhavati bharata
tadatmanam srjamy aham
vinasaya ca duskrtam
sambhavami yuge yuge
“Whenever and wherever there is a decrease in religious principles and a predominant rise in irreligion, at that time I descend Myself. To deliver the pious and annihilate the miscreants, as well as to reestablish the principles of religion, I Myself appear, millennium after millennium.” The Lord appears in order to execute two kinds of activities — to kill the demons and to protect the devotees. When the devotees are too disturbed by the demons, the Lord certainly appears in different incarnations to give the devotees protection. The devotees following in the footsteps of Prahlada Maharaja should not be disturbed by the demoniac activities of the nondevotees. Rather, they should stick to their principles as sincere servants of the Lord and rest assured that the demoniac activities directed against them will not be able to stop their devotional service.
