One who is attracted by the beauty of Radha and Krsna cannot be attracted by the false beauty of this material world. That is the difference between a demon and a godly person or devotee
SB Canto 3
The luster of the transcendental body of the Lord mocked the beauty of the coral mountain. The coral mountain is very beautifully dressed by the evening sky, but the yellow dress of the Lord mocked its beauty. There is gold on the summit of the mountain, but the Lord's helmet, bedecked with jewels, mocked it. The mountain's waterfalls, herbs, etc., with a panorama of flowers, seem like garlands, but the Lord's gigantic body, and His hands and legs, decorated with jewels, pearls, tulasī leaves and flower garlands, mocked the scene on the mountain.
The panoramic beauty of nature, which strikes one with wonder, may be taken as a perverted reflection of the transcendental body of the Lord. One who is therefore attracted by the beauty of the Lord is no longer attracted by the beauty of material nature, although he does not minimize its beauty. In Bhagavad-gītā (2.59) it is described that one who is attracted by param, the Supreme, is no longer attracted by anything inferior.
Adorned with dark tresses, she hid herself, as it were, out of shyness. Upon seeing that girl, the asuras were all infatuated with an appetite for sex.
The difference between demons and demigods is that a beautiful woman very easily attracts the minds of demons, but she cannot attract the mind of a godly person. A godly person is full of knowledge, and a demoniac person is full of ignorance. Just as a child is attracted by a beautiful doll, similarly a demon, who is less intelligent and full of ignorance, is attracted by material beauty and an appetite for sex. The godly person knows that this nicely dressed and ornamented attraction of high breasts, high hips, beautiful nose and fair complexion is māyā. All the beauty a woman can display is only a combination of flesh and blood. Śrī Śaṅkarācārya has advised all persons not to be attracted by the interaction of flesh and blood; they should be attracted by the real beauty In spiritual life. The real beauty is Kṛṣṇa and Rādhā. One who is attracted by the beauty of Rādhā and Kṛṣṇa cannot be attracted by the false beauty of this material world. That is the difference between a demon and a godly person or devotee.
