Devotee (3): Śrīla Prabhupāda, if after finishing one's sixteen rounds of the mahā-mantra...
Prabhupāda: Hm?
Devotee (3): ... Hare Kṛṣṇa, is it all right to...
Prabhupāda: It is not finished. If you have got time, if, if you haven't got to do anything else, you can continue, (laughter) sixteen hundred. It is not mechanical: "Now I have finished sixteen rounds, that's all." Why sixteen rounds? You chant sixteen hundred rounds. That is minimum, because you cannot concentrate your mind in chanting, you have no attachment for chanting, that is a, a regulative principle. You must. You must finish this. Otherwise, those who are actually attached to the Hare Kṛṣṇa mahā-mantra, that, that Haridāsa Ṭhākura, they are chanting whole day and night. But you cannot imitate that. Your mind is not fixed up. Therefore it is minimum sixteen rounds. Not that "Because minimum sixteen, I cannot chant more." Why not more? You can chant more, more.
Devotee (3): Śrīla Prabhupāda, after, if, if we chant more than sixteen rounds, can we chant bhaja śrī-kṛṣṇa-caitanya in our japa? Is it all right...
Prabhupāda: No, no, śrī-kṛṣṇa-caitanya is for, in the beginning it is done. Now you go on chanting as much as you can. And if you chant śrī-kṛṣṇa-caitanya that is also very good. There is no prohibition.
