SB 3.18.2
dadarsa tatrabhijitam dhara-dharam
pronniyamanavanim agra-damstraya
musnantam aksna sva-ruco ’runa-sriya
jahasa caho vana-gocaro mrgah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
He saw there the all-powerful Personality of Godhead in His boar incarnation, bearing the earth upward on the ends of His tusks and robbing him of his splendor with His reddish eyes. The demon laughed: Oh, an amphibious beast!
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In a previous chapter we have discussed the incarnation of the Supreme Personality of Godhead as Varaha, the boar. While Varaha, with His tusks, engaged in uplifting the submerged earth from the depths of the waters, this great demon Hiranyaksa met Him and challenged Him, calling Him a beast. Demons cannot understand the incarnations of the Lord; they think that His incarnations as a fish or boar or tortoise are big beasts only. They misunderstand the body of the Supreme Personality of Godhead, even in His human form, and they deride His descent. In the Caitanya sampradaya there is sometimes a demoniac misconception about the descent of Nityananda Prabhu. Nityananda Prabhu’s body is spiritual, but demoniac persons consider the body of the Supreme Personality to be material, just like ours. Avajananti mam mudhah: persons who have no intelligence deride the transcendental form of the Lord as material.
