Kṛṣṇa-kīrtana means... Just like we perform kīrtana with khol, karatāla, this is also kṛṣṇa-kīrtana. And to write books, that is also kṛṣṇa-kīrtana. And to read books, that is also kṛṣṇa-kīrtana. Not that simply this kīrtana is kīrtana. If you write books about Kṛṣṇa, if you read books about Kṛṣṇa, if you talk about Kṛṣṇa, you think of Kṛṣṇa, you worship Kṛṣṇa, you cook for Kṛṣṇa, you eat for Kṛṣṇa—so that is kṛṣṇa-kīrtana.
Therefore gosvāmī means twenty-four hours engaged in kṛṣṇa-kīrtana, in this way or that way. Kṛṣṇotkīrtana-gāna-nartana-parau. How? Premāmṛtāmbho-nidhī. Because they were merged into the ocean of kṛṣṇa-prema. Unless we have got kṛṣṇa-prema, love for Kṛṣṇa, how we can remain satisfied simply in the business of Kṛṣṇa? That is not possible. Those who have not developed love for Kṛṣṇa, they cannot be engaged twenty-four hours in the business of Kṛṣṇa. We should consider that... We should save time always to be absorbed in Kṛṣṇa business. The period we sleep, that is wasted. That is wasted. So we shall try to save time. Kīrtanīyaḥ sadā hariḥ (CC Adi 17.31). Hari is another name of Kṛṣṇa. Sadā, twenty-four hours. Actually, the Gosvāmīs used to do. They are our examples. They were sleeping not more that two hours or utmost, three hours. So nidrāhāra-vihārakādi-vijitau **. They conquered over. This is gosvāmī. They conquered over these things. What is that? Nidrāhāra, nidrā, āhāra, vihāra. Vihāra means sense enjoyment, and āhāra means eating or collecting. Generally, eating. And nidrā. Nidrāhāra-vihārakādi-vijitau. Conquered. That is Vaiṣṇava. Not that out of twenty-four hours, thirty-six hours sleeping. (laughter) And at the same time, passing on as gosvāmī. What is this go...? Go-dāsa. They are go-dāsa. Go means senses, and dāsa means servant.
So our policy should be, instead of becoming servant of the senses, we have to become servant of Kṛṣṇa. This is gosvāmī. Because unless you conquer over, senses will always ask you, "Please eat, please sleep, please have sexual intercourse. Please have this, please have this." This is material life. This is material life, subjected to the dictation of the senses. That is material life.
