Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Appearing in bodies like those of an ordinary fish, tortoise and hog, You exhibit activities impossible for such creatures to perform — extraordinary, incomparable, transcendental activities of unlimited power and strength. These bodies of Yours, therefore, are not made of material elements, but are incarnations of Your Supreme Personality. You are the same Supreme Personality of Godhead, who have now appeared, with full potency, for the benefit of all living entities within this material world.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated in Bhagavad-gita (4.7-8):
yada yada hi dharmasya
glanir bhavati bharata
abhyutthanam adharmasya
tadatmanam srjamy aham
paritranaya sadhunam
vinasaya ca duskrtam
dharma-samsthapanarthaya
sambhavami yuge yuge
Krsna appears as an incarnation when real spiritual life declines and when rogues and thieves increase to disturb the situation of the world. Unfortunate, less intelligent persons, bereft of devotional service, cannot understand the Lord’s activities, and therefore such persons describe these activities as kalpana mythology or imagination because they are rascals and the lowest of men (na mam duskrtino mudhah prapadyante naradhamah). Such men cannot understand that the events described by Vyasadeva in the Puranas and other sastras are not fictitious or imaginary, but factual.
Krsna, in His full, unlimited potency, here shows that He is the Supreme Personality of Godhead, for although the two trees were so large and sturdy that even many elephants could not move them, Krsna, as a child, exhibited such extraordinary strength that they fell down with a great sound. From the very beginning, by killing Putana, Sakatasura and Trnavartasura, by causing the trees to fall, and by showing the entire universe within His mouth, Krsna proved that He is the Supreme Personality of Godhead. The lowest of men (mudhas), because of sinful activities, cannot understand this, but devotees can accept it without a doubt. Thus the position of a devotee is different from that of a nondevotee.
