Kṛṣṇa consciousness is so nice that if one gets Kṛṣṇa consciousness, yaṁ labdhvā cāparaṁ lābhaṁ, aparaṁ lābhaṁ, any other benefit or gain is never considered. This is so nice. We are hankering after getting this, that, this, that, this, that, so many things. Dehi, dehi, dehi, dehi. But as soon as you get Kṛṣṇa consciousness, you will be satisfied. As Dhruva Mahārāja said, svāmin kṛtārtho 'smi varaṁ na yāce (CC Madhya 22.42). Just like Prahlāda Mahārāja. He was offered all benediction: "My dear Prahlāda, whatever you like, you can ask." He never asked anything. But he was so kind. That is the example of a Vaiṣṇava son in the family. Despite so much troubles given by his father, still, he begged from Narasiṁha-deva, "My Lord, my father has committed so many offenses. Kindly give him liberation." He did not ask anything for himself. So Hiraṇya . . . Narahari, Nṛsiṁha-deva, immediately said, "Why do you speak of your father? Your father's father, his father, fourteen generations—all liberated because a son like you is in this family." So this is the benefit. If a son becomes a pure Vaiṣṇava, devotee, he can deliver fourteen generations. That is a special prerogative because he is born in a certain family. So what we can give service to the family, nation, materially? If we become devotee, we can give best service to the nation, to the family, to the humanity. That is the philosophy.
So our Kṛṣṇa consciousness movement is preaching this philosophy that, "You take to Kṛṣṇa consciousness; your life will be perfect." And the method is very simple. It can be . . . there is no secrecy. Just like this evening I was talking with a boy. He has got a mantra, very secret. But we say we have no secret mantra. Our mantra, Hare Kṛṣṇa, is open to everyone. Why it should be secret? If by chanting Hare Kṛṣṇa mantra we can approach God, the Supreme Personality of Godhead, why it should remain secret? It should be distributed like anything so that everyone can go. So there is no secrecy. A secret mantra we don't approve. It must be very open. There is no secret. The śāstra never says that mantra can be secret.
