Anyone who is not in perfect knowledge, he should not take the position of talking like a learned man. That is cheating and that is foolishness. First of all you know things as they are. Then talk. Otherwise, it is said that it is better not to talk than to talk foolish. It is better to stop talking. Therefore, sometimes in spiritual advancement there is a process, maunam. Maunam means not to talk. Those who are too much foolish, the spiritual master orders him, "Don't talk. Please remain silent." That's all. Because if you talk, you'll talk simply nonsense. Why should you spoil your energy by such nonsense talking? Better stop. The meditation is also like that also. Instead of talking or doing nonsense, if one is remaining silent for some time, it is little good for him.
But this meditation and maunam, silence, is not meant for the devotees. They are meant for the lesser intelligent class of men. Devotees' business is always to talk about Kṛṣṇa. Why they should stop talking, maunam? No. Kīrtanīyaḥ sadā hariḥ (CC Adi 17.31). Caitanya Mahāprabhu says that one has to chant and talk of Kṛṣṇa twenty-four hours. Where is the question of maunam, silence? There is no question of silence. Silence is for those who are nonsense. "Be silent. Don't talk." For them. At least they practice silence means at least they stop talking nonsense.
But those who are actually advanced, for them there is no such restriction. Vācāṁsi vaikuṇṭha-guṇānuvarṇane (SB 9.4.18). We should use our talking power for describing the glories of the Lord. Vaikuṇṭha-guṇānuvarṇane. That is kīrtana. That is chanting. Abhavad vaiyāsakiḥ kīrtane (Bhakti-rasāmṛta-sindhu 1.2.265). Just like for seven days when Parīkṣit Mahārāja was going to die . . . he had only seven days left. So twenty-four hours without any eating or without any drinking a drop of water, he went on hearing from Śukadeva Gosvāmī. And similarly, Śukadeva Gosvāmī also went on speaking, speaking Śrīmad-Bhāgavatam. Śrī-viṣṇu-śravane parīkṣit. They got, both of them got salvation back to home, back to Godhead. How? One was hearing, and one was chanting. These two process. Parīkṣit Mahārāja was hearing, and Śukadeva Gosvāmī was chanting. And what was the subject matter? Kṛṣṇa. That's all.
So Kṛṣṇa subject matter is so nice that simply you do not do anything. Simply hear, that's all. You have got God-given ear. You can hear. Sit down. Sthāne sthitāḥ śruti-gatāṁ tanu-vāṅ-manobhiḥ (SB 10.14.3). Śrutigatam. Śruti means this ear. Śrota-pantaḥ. This is called śrota-pantaḥ: getting knowledge by hearing. Satāṁ prasaṅgān mama vīrya-samvido bhavanty hṛtkārṇa-rasāyana-kathāḥ, satāṁ prasaṅgāt (SB 3.25.25), when there is actually sat-sanga. Sat-sanga means this talking of Kṛṣṇa, hearing about Kṛṣṇa. When there is . . . there is no business. Not like a rented reciter or a paid reciter, who is earning money by reciting. No, no. Not to hear from him. Actually he's self-realized who is working for the Lord, from satām.
