Lord Kṛṣṇa's name is Madana-mohana, for He can subdue the god Cupid, or lust. Only by engaging in the service of Madana-mohana can one curb the dictates of Madana, Cupid. Otherwise, attempts to control the senses will fail.
Instead of being attracted by material beauty, if one is accustomed to be attracted by the beauty of Rādhārāṇī and Kṛṣṇa, then the statement of Bhagavad-gītā, paraḿ dṛṣṭvā nivartate, holds true. When one is attracted by the transcendental beauty of Rādhā and Kṛṣṇa, he is no longer attracted by material feminine beauty. That is the special significance of Rādhā-Kṛṣṇa worship. That is testified to by Yāmunācārya. He says, "Since I have become attracted by the beauty of Rādhā and Kṛṣṇa, when there is attraction for a woman or a memory of sex life with a woman, I at once spit on it, and my face turns in disgust." When we are attracted by Madana-mohana and the beauty of Kṛṣṇa and His consorts, then the shackles of conditioned life, cannot attract us.
