Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 2
ददर्श तत्राभिजितं धराधरंप्रोन्नीयमानावनिमग्रदंष्ट्रया ।मुष्णन्तमक्ष्णा स्वरुचोऽरुणश्रियाजहास चाहो वनगोचरो मृग: ॥ २ ॥
dadarśa tatrābhijitaṁ dharā-dharaṁpronnīyamānāvanim agra-daṁṣṭrayāmuṣṇantam akṣṇā sva-ruco ’ruṇa-śriyājahāsa cāho vana-gocaro mṛgaḥ
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!
In a previous chapter we have discussed the incarnation of the Supreme Personality of Godhead as Varāha, the boar. While Varāha, with His tusks, engaged in uplifting the submerged earth from the depths of the waters, this great demon Hiraṇyākṣa 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 sampradāya there is sometimes a demoniac misconception about the descent of Nityānanda Prabhu. Nityānanda Prabhu’s body is spiritual, but demoniac persons consider the body of the Supreme Personality to be material, just like ours. Avajānanti māṁ mūḍhāḥ: persons who have no intelligence deride the transcendental form of the Lord as material.
