Caitanya Mahāprabhu said that bhārata-bhūmite manuṣya-janma haila yāra: (CC Adi 9.41) "Anyone..." He is ordering all Indians. Bhārata-bhūmite means all Indians. He does not say the Hindus or the Bengalis or these Punjabis. No. He says particularly, "Any person who has taken his birth in this land of Bhāratavarṣa," janma sārthaka kari, "you just perfect your life. Just perfect your life," and kara paropakāra, "and distribute this knowledge for benefit of all other people."
So this injunction is received, as Caitanya Mahāprabhu says, that "First of all make your life perfect. Don't try to preach without becoming yourself perfect." The nonsense thing is going on in this world that so-called preachers, they have not perfected their life, but they have become preachers. They have not already perfected their life, and they have become preacher. Therefore they are bringing so many nonsense things and misleading persons, Vedāntists and Vedānta Society, yogis, this or that. But they are not themselves perfect. So Caitanya Mahāprabhu said that "Before becoming preacher, before endeavoring yourself to do good to others, you just perfect yourself." "Physician, heal thyself." Physician, you are yourself diseased. How you can become a physician? People will, at once, will be detracted, "Oh, this doctor, this medical man, he's suffering from fever, and he's treating my fever." So there will be no, I mean to say, effect. So Caitanya Mahāprabhu says, or His spiritual master says, that kṛṣṇa-nāma upadeśi' tāra' sarva-jana: "First of all You have perfected Yourself by chanting Hare Kṛṣṇa. You have come to the perfectional stage. Now You have got the symptoms of emotion. Now You can preach Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare."
