So whatever Kṛṣṇa consciousness movement is going forward, it is due to Śrī Caitanya Mahāprabhu's magnanimous compassion for the poor people suffering in this Kali-yuga. Otherwise, to become Kṛṣṇa conscious is not very easy job, is not easy job. So those who are getting the chance of becoming Kṛṣṇa conscious by the mercy of Śrī Caitanya Mahāprabhu, they should not lose the opportunity. It will be suicidal. Don't fall down. It is very easy. Simply chanting by Hare Kṛṣṇa mantra, not always, twenty-four hours, although Caitanya Mahāprabhu recommends, kīrtanīyaḥ sadā hariḥ (CC Adi 17.31), always chant. That is the principle. But we cannot do that because we are so much overwhelmed by the influence of Kali. So at least sixteen rounds. Don't miss this. Don't miss this. What is the difficulty, sixteen rounds? At most it will take two hours. You have got twenty-four hours. You want to sleep; all right, sleep, ten hours sleep. That is not recommended. Don't sleep more than six hours. But they want to sleep. They want to sleep twenty-four hours. That is their desire in Kali-yuga. But, no. Then you'll be wasting time. Minimize eating, sleeping, mating and defending. When it is nil, that is perfection.
Because these are bodily necessities. Eating, sleeping, mating, defending that is bodily necessities. But I am not this body. Dehino 'smin yathā dehe kaumāram... (BG 2.13). So that realization takes time. But when we are actually advancing in Kṛṣṇa consciousness, we must know our duty. Sleeping not more than six hours. Utmost eight hours. Utmost, those who cannot control. But not ten hours, twelve hours, fifteen hours, no. Then what is the use of...? Somebody went to see one advanced devotee, and at nine o'clock he was sleeping. And he's advanced devotee. Eh? Is not that? So what is...? What kind of devotee he is? Devotee must rise early in the morning, by four o'clock. By five o'clock, he must finish his bathing and other things. Then he takes to chanting and so many... Twenty-four hours' business must be there. So sleeping is not good. The Gosvāmīs used to sleep only two hours. I also write at night book, and I also sleep, not more than three hours. But I take sometimes little, sleep more. Not like... I don't imitate the Gosvāmīs. That is not possible. But as far as possible, so everyone should try to avoid. And avoid sleeping means if we eat less, then we'll avoid. Eating, sleeping. After eating, there is sleeping. So if we eat more, then more sleeping. If we eat less, then less sleeping. Eating, sleeping, mating. And mating should be avoided. That is a great stricture. Sex life should be minimized as far as possible. Therefore we have got this restriction, "No illicit sex." Sex life, we don't say... That you cannot do, nobody can do. Therefore sex life means married life, a little concession. A license, "All right, you take this license." But not illicit sex. Then you'll never be able.
So eating, sleeping, mating and defending. And defending, we are defending in so many ways, but still, war is there, and the onslaught of material nature... Your country is defending so nicely, but now the petrol is taken away. You cannot defend. Similarly, everything can be taken away at any moment. So depend on Kṛṣṇa for defending, defenses. Avaśya rakṣibe kṛṣṇa. This is called surrender. Surrender, means... Kṛṣṇa says that "You surrender unto Me," sarva-dharmān parityajya (BG 18.66). Let us believe this, that "Kṛṣṇa is asking to surrender. Let me surrender. He must protect me in danger." That is called surrender.
