Yajña, dāna. Brahmacārī should offer yajña, gṛhastha should give in charity, and sannyāsī, vānaprastha, should undergo tapasya. Yajña-dāna-tapaḥ-karma. We should not give up this, these things. "Because I have become sannyāsī—I have given up my family—therefore I give up also all other regulative principles." No. That you cannot. The sannyāsī means... Sannyāsī, they have got also rules and regulation. Caitanya Mahāprabhu very rigidly followed. He did not lie down even on a quilt, only one naked cloth. He did not use... And no woman should come to offer Him obeisances very near. They must do it from a distant place. He was so strict. One of His personal associates, Haridāsa, Junior Haridāsa, he simply glanced over a young woman with lusty desire. He immediately rejected him: "Ask Haridāsa not to come anymore." So He never excused him very strictly. And Haridāsa, being disappointed, he... On his behalf, very close devotees like Sārvabhauma Bhaṭṭācārya, Rāmānanda Rāya, big, big devotees, Svarūpa Dāmodara and others, requested Lord Caitanya Mahāprabhu that "He has committed mistake, but he is Your personal servant. Kindly excuse him." Then Caitanya Mahāprabhu said, "All right, then you can call him. You live with him. I shall go from here. You live with him; let Me go away." He was so strict. Then, when Haridāsa Ṭhākura Junior... The senior is another. Then he committed suicide—"Now it is hopeless. I cannot come to Caitanya Mahāprabhu." He committed suicide. And when this information was given to Caitanya Mahāprabhu, He did not regret. "Oh, this man has committed suicide? Yes, it is right." He said, "Yes, it is right." So He was so strict.
Therefore in the śāstra it is forbidden that Kali-yuga is very difficult to follow the rules and regulation of a sannyāsī; therefore better not to accept sannyāsa. Kalau pañca vivarjayet. Sannyāsaṁ pala-paitṛkam devareṇa sutotpattiṁ kalau pañca vivarjayet (CC Adi 17.164). Instead of becoming a false sannyāsī, do not accept sannyāsa. This is the injunction of the śāstra. But for preaching work we have to get the help of some sannyāsī, but we should remember that we are in Kali-yuga. We should not be sentimentally very much anxious—"Please give me sannyāsa, give me sannyāsa"—and then fall down and go to hell. That is not good. That is not good. If one is able to strictly follow the sannyāsa rules and regulation, he should take. Otherwise, Kṛṣṇa has said that sannyāsa, real sannyāsa, means one who does not take any remuneration for his service to Kṛṣṇa. That is sannyāsa. Anāśritaḥ karma-phalaṁ kāryaṁ karma karoti yaḥ sa sannyāsī (BG 6.1). "It is my duty. I am eternal servant of Kṛṣṇa. To serve Kṛṣṇa is my duty." Kāryam: "I must do it." Actually that mentality is sannyāsa. It doesn't matter whether we have changed the dress or not, but if we decide it, that "I am eternal servant of Kṛṣṇa; my only duty is to serve Kṛṣṇa," that is sannyāsa.
So better we should try to stay in this determination than to accept the sannyāsa order by changing the dress and then again we fall down. That is not very good. There are instances like that, but it is not at all good. We should not trust the mind. And even we take, we should be very, very vigilant on the mind. Viśvāso naiva kartavyam. Cāṇakya Paṇḍita says, (chuckles) viśvāso naiva kartavyaḥ strīṣu rāja-kuleṣu ca. "Never trust woman and politician." He was a politician, and his wife was kidnapped. He had very bad experience of these two things, Cāṇakya Paṇḍita. Therefore he gave this injunction, viśvāso naiva kartavyaḥ strīṣu rāja-kuleṣu ca: "Never trust woman and politician." So Cāṇakya Paṇḍita was not inexperienced; he was very experienced. All the ślokas of Cāṇakya Paṇḍita—very useful for daily affairs. So similarly, we should not trust the mind, that "Now I have become liberated." Never think so. We should always remember that liberation is not so easy thing, but if we follow the rules and regulation, then there is every possibility of becoming liberated.
But this is the business in the human...Tapaḥ. That is the instruction. Tapo divyaṁ putrakā yena śuddhyed sattva (SB 5.5.1). You must purify your existence. This is the only business of human life, tapasya. So tapasya means brahmacārī. Tapasā brahmacaryeṇa (SB 6.1.13). Tapasya means brahmacaryeṇa, no sex life. That is tapasya, real tapasya. Tapasā brahmacaryeṇa śamena damena ca. Even if you practice yoga system, this regulation must be followed, celibacy, not that fashion yoga system. Now in your country there are so many transcendental yogis, and they say, "Yes, whatever you like, you can do. God has given you senses, you must enjoy." These are manufactured cheating processes. But actually yoga means indriya-samyamaḥ. Yoga indriya-saṁyamaḥ. Not gymnastic. That is not yoga. Yoga indriya-saṁyamaḥ. Mind control. The same thing, mind control. So mind you cannot control unless your mind is fully engaged in the service of Kṛṣṇa. Sa vai manaḥ kṛṣṇa padāravindayor vacāṁsi vaikuṇṭha-guṇānuvarṇane (SB 9.4.18). These are the examples.
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. 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. 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.
