One who has tasted the beauty of the Supreme Lord Kṛṣṇa, in the course of his advancement in Kṛṣṇa consciousness, no longer has a taste for dead, material things.
(Bhagavad-Gita----2:59----purport).

There was nothing comparable to the bodily features of Lord Kṛṣṇa when He was present in this world. The most beautiful object in the material world may be compared to the blue lotus flower or the full moon in the sky, but even the lotus flower and the moon were defeated by the beauty of the bodily features of Lord Kṛṣṇa, and this was certified by the demigods, the most beautiful living creatures in the universe. The demigods thought that Lord Kṛṣṇa, like themselves, was also created by Lord Brahmā, but in fact Brahmā was created by Lord Kṛṣṇa. It was not within the power of Brahmā to create the transcendental beauty of the Supreme Lord. No one is the creator of Kṛṣṇa; rather, He is the creator of everyone. As He says in Bhagavad-gītā (10.8), ahaṁ sarvasya prabhavo mattaḥ sarvaṁ pravartate.
(Srimad Bhagavatam----3:2:13----purport).

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.
(Srimad Bhagavatam----3:20:31----purport).

The beauty of Kṛṣṇa's face was much more appreciated by the gopīs than by His friends the cowherd boys or even by Yaśodā Mātā, who was also interested in decorating the face of Kṛṣṇa.
(Srimad Bhagavatam----9:24:65----purport).

The Supreme Personality of Godhead, Kṛṣṇa, is the reservoir of all beauty. All beautiful things emanate from Him, and His personal form is so attractive that it steals the eyes away from all other objects, which then seem devoid of beauty in comparison to Him. When Lord Kṛṣṇa was on the earth, He attracted the eyes of all people. When Kṛṣṇa spoke, His words attracted the minds of all who remembered them. By seeing the footsteps of Lord Kṛṣṇa, people became attracted to Him, and thus they wanted to offer their bodily activities to the Lord as His followers. In this way Kṛṣṇa very easily spread His glories, which are sung throughout the world by the most sublime and essential Vedic verses. Lord Kṛṣṇa considered that simply by hearing and chanting those glories, conditioned souls born in the future would cross beyond the darkness of ignorance. Being satisfied with this arrangement, He left for His desired destination.
(Srimad Bhagavatam----11:1:6-7---translation).

The beauty of Kṛṣṇa has one natural strength: it thrills the hearts of all men and women, beginning with Lord Kṛṣṇa Himself.
(Sri Caitanya Caritamrta----1:4:147----translation).

The beauty of Lord Kṛṣṇa increases at the sight of the beauty of the gopīs. And the more the gopīs see Lord Kṛṣṇa's beauty, the more their beauty increases.
(Sri Caitanya Caritamrta----1:4:192----translation).

"Although Kṛṣṇa's unparalleled beauty is the topmost sweetness of love of Godhead, His sweetness increases unlimitedly when He is in the company of the gopīs. Consequently Kṛṣṇa's exchange of love with the gopīs is the topmost perfection of love of Godhead."
(Sri Caitanya Caritamrta----1:4:192----translation).

"Great sages conquer the mind and senses by practicing the mystic yoga system and controlling the breath. Thus engaging in mystic yoga, they see the Supersoul within their hearts and ultimately enter into impersonal Brahman. But even the enemies of the Supreme Personality of Godhead attain that position simply by thinking of the Supreme Lord. However, the damsels of Vraja, the gopīs, being attracted by the beauty of Kṛṣṇa, simply wanted to embrace Him and His arms, which are like serpents. Thus the gopīs ultimately tasted the nectar of the lotus feet of the Lord. Similarly, we Upaniṣads can also taste the nectar of His lotus feet by following in the footsteps of the gopīs."
(Sri Caitanya Caritamrta----2:8:224----translation).

"Ornaments caress that body, but the transcendental body of Kṛṣṇa is so beautiful that it beautifies the ornaments He wears. Therefore Kṛṣṇa's body is said to be the ornament of ornaments. Enhancing the wonderful beauty of Kṛṣṇa is His three-curved style of standing. Above all these beautiful features, Kṛṣṇa's eyes dance and move obliquely, acting like arrows to pierce the minds of Śrīmatī Rādhārāṇī and the gopīs. When the arrow succeeds in hitting its target, their minds become agitated."
(Sri Caitanya Caritamrta----2:21:105----translation).

"The beauty of Kṛṣṇa's body is so attractive that it attracts not only the demigods and other living entities within this material world but the personalities of the spiritual sky as well, including the Nārāyaṇas, who are expansions of Kṛṣṇa's personality. The minds of the Nārāyaṇas are thus attracted by the beauty of Kṛṣṇa's body. In addition, the goddesses of fortune (Lakṣmīs), who are the wives of the Nārāyaṇas and are the women described in the Vedas as most chaste, are also attracted by the wonderful beauty of Kṛṣṇa."
(Sri Caitanya Caritamrta----2:21:106----translation).

"The bodily beauty of Śrī Kṛṣṇa is like a wave in the ocean of eternal youth. In that great ocean is the whirlpool of the awakening of ecstatic love. The vibration of Kṛṣṇa's flute is like a whirlwind, and the flickering minds of the gopīs are like straws and dry leaves. After they fall down in the whirlwind, they never rise again but remain eternally at the lotus feet of Kṛṣṇa."
(Sri Caitanya Caritamrta----2:21:113----translation).

"The sweetness of Kṛṣṇa's beauty enjoyed by the gopīs is unparalleled. Nothing is equal to or greater than such ecstatic sweetness. Even the predominating Deities of the Vaikuṇṭha planets, the Nārāyaṇas, do not possess such sweetness. Indeed, none of the incarnations of Kṛṣṇa up to Nārāyaṇa possess such transcendental beauty."
(Sri Caitanya Caritamrta----2:21:115----translation).

"The beauty of Kṛṣṇa's smile is the sweetest feature of all. His smile is like a full moon that spreads its rays throughout the three worlds—Goloka Vṛndāvana, the spiritual sky of the Vaikuṇṭhas, and Devī-dhāma, the material world. Thus Kṛṣṇa's shining beauty spreads in all ten directions."
(Sri Caitanya Caritamrta----2:21:139----translation).

"The beauty of Kṛṣṇa's eyes surpasses the beauty of white lotus flowers, His yellow garments surpass the brilliance of fresh decorations of kuṅkuma, His ornaments of selected forest flowers subdue the hankering for the best of garments, and His bodily beauty possesses mind-attracting splendor greater than the jewels known as marakata-maṇi (emeralds)."
(Sri Caitanya Caritamrta----3:1:165----translation).

Śrī Caitanya Mahāprabhu said, "Though the hearts of the gopīs are like high-standing hills, they are inundated by the waves of the nectarean ocean of Kṛṣṇa's beauty. His sweet voice enters their ears and gives them transcendental bliss, the touch of His body is cooler than millions and millions of moons together, and the nectar of His bodily fragrance overfloods the entire world. O My dear friend, that Kṛṣṇa, who is the son of Nanda Mahārāja and whose lips are exactly like nectar, is attracting My five senses by force."
(Sri Caitanya Caritamrta----3:15:14----translation).

"Lord Śrī Kṛṣṇa's beauty, the sound of His words and the vibration of His flute, His touch, His fragrance and the taste of His lips are full of an indescribable sweetness. When all these features attract My five senses at once, My senses all ride together on the single horse of My mind but want to go in five different directions."
(Sri Caitanya Caritamrta----3:15:15----translation).
