The gopīs' minds are always engaged in relishing the sweetness of Kṛṣṇa's body. He is the ocean of beauty, and His beautiful face and smile and the luster of His body are all-attractive to the minds of the gopīs.
(Teachings of Lord Caitanya).

The body of Kṛṣṇa, the ocean of the eternal beauty of youth, can be seen to move in waves of beauty. There is a whirlwind at the sound of His flute, and those waves and that whirlwind make the hearts of the gopīs flutter like dry leaves on trees, and when those leaves fall down at Kṛṣṇa's lotus feet, they can never rise up again.
(Teachings of Lord Caitanya).

The consciousness of each woman within the three worlds is certainly like a high hill, but the sweetness of Kṛṣṇa’s beauty is like an ocean. Even a drop of water from that ocean can flood the entire world and submerge all the high hills of consciousness.
(Sri Caitanya Caritamrta------3:15:19------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).

The beauty of the son of Mahārāja Nanda is incomparable. Nothing is higher than His beauty, and nothing can equal it. His beauty is like waves in an oceanof nectar. This beauty is attractive both for moving and for nonmoving objects.”
(Sri Caitanya Caritamrta------2:12:215------purport).

When there is a combination of kapha, pitta and vāyu, the three bodily elements, there occurs sannipāti, or a convulsive disease. Lord Caitanya said, “This disease of Mine is caused by the personal features of Lord Kṛṣṇa. The three elements are the beauty of Kṛṣṇa’s body, the beauty of His face, and the beauty of His smile. Stricken by these three beauties, My mind goes into convulsions. It wishes to drink the ocean of Kṛṣṇa’s beauty, but because I am undergoing convulsions, My physician, who is Śrī Kṛṣṇa Himself, does not even allow Me to take a drop of water from that ocean.” Śrī Caitanya Mahāprabhu was ecstatic in this way because He was presenting Himself in the mood of the gopīs. The gopīs wanted to drink the ocean of sweetness arising from the bodily features of Kṛṣṇa, but Kṛṣṇa did not allow them to come near. Consequently their desire to meet Kṛṣṇa increased, and being unable to drink the ambrosia of Kṛṣṇa’s bodily features, they became very unhappy.
(Sri Caitanya Caritamrta------2:21:137------purport).
