Sarvabhauma Bhaṭṭācārya is offering his prayer to the Supreme Personality of Godhead, who has now assumed the form of Caitanya Mahāprabhu, vairāgya-vidyā-nija-bhakti-yoga-śikṣārtham (CC Madhya 6.254), just to teach people how to become a pure devotee of Kṛṣṇa. A pure devotee of Kṛṣṇa. So vairāgya-vidyā.
Just like Caitanya Mahāprabhu. He was only twenty-five . . . twenty-four years old. His lovable wife, beautiful wife, very very serving; mother, so affectionate mother; but He gave up everything, took sannyāsa. So much honor . . . Caitanya Mahāprabhu, when He was gṛhastha, He was so much honored that by His only direction of His finger, lakhs of people would immediately join Him as He started the civil disobedience movement against Kazi. So His position was very respectable in Nadia.
Young man, beautiful, His body. Nobody can compare with His beautiful body. Young wife, faithful wife, beautiful wife; mother, affectionate; position; everything. But He gave up everything. Vairāgya. This is called vairāgya, renouncement. If somebody has nothing to possess, if he says: "I have renounced everything," what is the meaning of renouncement? If you have something then you renounce, then there is meaning.
So Caitanya Mahāprabhu's renouncement is unique. Nobody can give up such happy home, his honor, his position, his affection from mother, wife, friends, students, everywhere
