Srila Prabhupada

So Caitanya Mahāprabhu also accepted sannyāsa in very young age, when He was only twenty-four years. So why? Tyaktvā tūrṇam, rājya-lakṣmīṁ dharmiṣṭha ārya-vacasā yad agād araṇyam (SB 11.5.34). Caitanya Mahāprabhu was very, very well situated. He was born in a very respectable high brāhmaṇa family, Jagannātha Miśra, and mother's side, the Nīlāmbara Cakravartī, he was very respectable brāhmaṇa. And Caitanya Mahāprabhu's learning, nobody could excel Him, He was so learned scholar. And when He was sixteen years old, He defeated one of the most learned scholar of India, Keśava Bhāratī. So learning, family . . . And wife? Personally goddess of fortune, Lakṣmīpriyā and Viṣṇupriyā, most beautiful and young. Viṣṇupriyā was His second wife; so faithful, so beautiful, personally goddess of fortune, such wife. And mother, most affectionate. There is no comparison with Śacī-mātā. So this was . . . And influence? When He was twenty years old, He could, by His command, gather 100,000 people to protest against Kazi, He was so popular. So popularity, born in high family, having good wife and good mother, everything complete—still, He took sannyāsa. Therefore it is said, pūrvatamair mahadbhiḥ. Why? Now, just to show mercy to the fallen souls. Māyā-mṛgaṁ dayitayā (SB 11.5.34). Just to show mercy to the fallen souls. This is the meaning of sannyāsa. One must be very merciful. Vaiṣṇavas, they are merciful. All devotees of God, Vaiṣṇava, they are merciful.

That is the mission of Śrī Caitanya Mahāprabhu. His mission is, especially to the Indians He says,
bhārata-bhūmite haila manuṣya-janma yāra
janma sārthaka kari' kara para-upakāra
(CC Adi 9.41)
Para-upakāra, just to do something good for others, for upakāra. So Caitanya Mahāprabhu says anyone who has taken birth in India, he should, bhārata-bhūmite manuṣya-janma haila yāra (CC Adi 9.41), anyone who has taken birth in India, for every one of them, it is the duty. Janma sārthaka kari': first of all make your life successful, janma sārthaka kari' kara para-upakāra, then you begin the welfare activities for all others. The idea is that India is enriched with Vedic knowledge, and those who are born in India, they should take advantage of this facility, especially those who are in the higher, topmost ranks, the brāhmaṇas, the kṣatriyas, the vaiśyas. Especially the brāhmaṇas. Take this education perfectly well, make your life perfect, and distribute the knowledge all over the world. This is your duty. That is the order of Śrī Caitanya Mahāprabhu.
