So Raghunātha dāsa Gosvāmī followed very strictly, Caitanya Mahāprabhu also followed very strictly, and the Rūpa-Sanātana Gosvāmī followed very strictly. Not that because one is living in Vṛndāvana with a short cut cloth and therefore he has become like Rūpa Gosvāmī... Rūpa Gosvāmī was fully engaged. Nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau lokānāṁ hita-kāriṇau. They were in Vṛndāvana, but they were always thinking how to do good to the people, to this material world. Just like Prahlāda Mahārāja. Śoce tato vimukha-cetasa (SB 7.9.43). Sādhu's concern is to think of the misled materialistic persons. They are always thinking, making plan how to elevate them, they are suffering. This is sādhu. Lokānāṁ hita-kāriṇau, sādhu, not that "I have changed my dress in such a way, and people out of sentiment will give me roti, and I shall eat and sleep." That is not sādhu. Sādhu... Bhagavān, Kṛṣṇa, says who is sādhu. Api cet su-durācāro bhajate mām ananya-bhāk sādhur eva sa mantavyaḥ (BG 9.30). That is sādhu. Who has fully dedicated his life for Kṛṣṇa, he is sādhu. Even he has got some bad habits... Bad habits? A sādhu cannot have bad habits because if one is sādhu, if in the beginning he has got some bad habit, that will be rectified. Śaṣvad bhavati dharmātmā. Kṣipraṁ bhavati dharmātmā śaśvac-chāntiṁ nigacchati (9.31). If he's actually sādhu, his bad habits will be rectified very soon, very soon, not that he's continuing his bad habits and also a sādhu. That cannot be. That is not sādhu. Maybe due to his past habits, he might have committed some mistake. That can be excused. But if he, in the name of sādhu and become a liberated person, he continues to do all nonsense, he's a cheater. He's not sādhu. Api cet su-durācāro. Cet, yadi, if, by chance, it is possible. But if he sticks to Kṛṣṇa consciousness, then kṣipraṁ bhavati dharmātmā śaśvac-chāntiṁ nigacchati. In the beginning there may be some mistake, but we must see that "Whether my mistakes are now correct?" That should be vigilance. Never trust the mind. That is the instruction here. Mind should not be trusted. My Guru Mahārāja used to say that "After getting up from your sleep, you take your shoes and beat your mind hundred times. This is your first business. And while going to bed, you take a broomstick and beat your mind hundred times. Then you can control your mind. Otherwise it is very difficult."
So this is... This beating with shoes and broomstick is also another tapasya. For men like us, who have no control over the mind, we should practice this tapasya, beating the mind with shoes and broomstick. Then it can be controlled. And swami means who has control over the mind. Vāco-vegam, krodha-vegam, udara-vegam, upastha-vegam, manasa-vegam, krodha-vegam, etān vegān yo viṣaheta dhīraḥ pṛthivīṁ sa śiṣyāt (NOI 1). This is Rūpa Gosvāmī's instruction. When we can control vāco-vegam... (child crying, Prabhupāda pauses) This is krandana-vegam. (laughs) They cannot control. They cannot control. Therefore they are child. The child can be excused, but if a person who is in the spiritual life, he cannot control, then hopeless. Then he's hopeless. This should be controlled. Vaco-vegam, krodha-vegam, udara-vegam, upastha vegam. But the most important thing is udara-vegam and jihvā-vegam. Jihvā-vegam, it is very controlled. Bhaktivinoda Ṭhākura said that "All the senses are there, but out of them, this jihvā is very dangerous." Tā'ra madhye jihvā ati lobhamoy sudurmati tā'ke jetā kaṭhina saṁsāre. It is very, very difficult to control the tongue.
