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.
