Kṛṣṇa Caitanya Mahāprabhu's contribution that, "You simply chant Hare Kṛṣṇa mantra. Then all perfection will come to you." All perfection will come. Very simple thing. It does not cost anything. If you chant Hare Kṛṣṇa mantra, there is no loss on your part. It does not cost you. It does not make you obliged to undergo so many severe penalties. No. You can chant at any moment. Kīrtanīyaḥ sadā hariḥ (CC Adi 17.31). We have seen practically. These boys, although they are very young, you'll find they have got these beads. I have asked them to chant always. They are chanting as far as possible.
So this, this process has to be adopted, if you're actually serious to understand Kṛṣṇa. And if you do not try to understand Kṛṣṇa, then you are making suicide. Ātma-hā. They have been described in the śāstra: ātma-hā. If I cut my throat, my self, then who can save me? So people do not understand it. And Narottama dāsa Ṭhākura, who understands, he has sung, hari hari biphale janama goṅāinu, manuṣya-janama pāiyā, rādhā-kṛṣṇa nā bhajiyā, jāniyā śuniyā biṣa khāinu. So it is our duty of course, as servant of Kṛṣṇa, to awaken everyone to Kṛṣṇa consciousness by this process of saṅkīrtana movement, but people should take it very seriously, that without taking to Kṛṣṇa consciousness, one is making suicide—he's cutting his own throat, or drinking poison. If you like to drink poison, no can . . . nobody can check you, that's a fact. If you want to cut your throat your self, nobody can check you. But this is not very good business. We have got this human form of life to understand Kṛṣṇa. That is the . . . our only business. That is Caitanya Mahāprabhu's teaching. And Kṛṣṇa is teaching personally in the Bhagavad-gītā, and why should we not take advantage of these things and make our life successful? Why we should be so much foolish? But they are. I do not why they are not taking to Kṛṣṇa consciousness. They will take to so many other, bogus thing, but they will not take Kṛṣṇa.
But anyway, if one is serious, then he has to follow this principle, vīta-rāga-bhaya-krodhāḥ (BG 2.56). Bhaya-krodhāḥ. Bhaya means fearfulness. That is one of the qualification of conditioned life. Āhāra-nidrā-bhaya-maithuna. Four things. So long we are in conditioned stage, this material body, these things are demands: to eat, to sleep and to become fearful, defend, defend and . . . āhāra-nidrā, and maithuna, sexual intercourse. These are the four demands of this material body. And everyone is busy—how to eat . . . you'll find in Bombay city so many restaurants. Every step a restaurant. Eating. That is going on. Every city, all over the world, everywhere, eating. And then sleeping, nice apartment. And then defense measure. And then very happily have sexual intercourse. These are the demands.
