This niṣṭhā is not invented by us. Pūrvatamair mahadbhiḥ upāsitām. All great predecessors . . . there were other sannyāsīs, Rāmānujācārya, Madhvācārya, even Caitanya Mahāprabhu, He was a sannyāsī. So pūrvatamair mahadbhiḥ upāsitām. These actions were executed by our previous ācāryas. Pūrvatamair mahadbhiḥ upāsitām. Mahadbhiḥ. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). You have to follow the ācārya. Ācārya upāsana. Aham . . . the, what will be the result? Now, ahaṁ tariṣyāmi. I shall cross over . . . tariṣyāmi. Duranta-pāram: the extensive, unlimitedly extensive, the ocean of material existence. Ahaṁ tariṣyāmi duranta-pāraṁ tama. Tama means this material world, which is darkness. Because our business is to go out of this darkness to the light. Tamasi mā jyotir gama. We have to go to the light.
So this is the process. Aham . . . and what is that process? Tama mukundāṅghri-niṣevayaiva. Mukunda means Kṛṣṇa, one who gives liberation. Hari. Hari means one who takes away all your sinful activities. Ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi (BG 18.66). He's taking; therefore His name is Hari. Mukundāṅghri. Another name is Mukunda. Mukunda means . . . muk means mukti, and ānanda means bliss. Kṛṣṇa gives you mukti, deliverance, deliverance from this tama, this material world, and gives you transcendental bliss; therefore His name is Mukunda. Mukundāṅghri: the lotus feet of Mukunda. Niṣevayaiva. Simply by serving the lotus feet of Mukunda, I can do this. This is the sum and substance.
So this sannyāsa order, although it is prohibited in this age . . . because so many rascals will accept sannyāsa and do all nonsense things; therefore sannyāsa is prohibited. Just like nowadays in Kali-yuga the . . . some of the sannyāsīs, they are eating meat. Disastrous. So this kind of rascal sannyāsism is prohibited in the śāstra. Sannyāsaṁ pala-paitṛkam, devareṇa sutotpattiṁ kalau pañca vivarjayet (CC Adi 17.164). But Caitanya Mahāprabhu and Vaiṣṇava ācāryas, they took sannyāsa for preaching work, not for doing rascaldom. Preaching work. So mukunda ahaṁ niṣevaye. Mukundāṅghri-niṣevayaiva. Simply by serving . . . Mukunda, Kṛṣṇa, what does He want? He wants that this philosophy of Kṛṣṇa, Bhagavad-gītā, should be spread all over the world. You take up this determination and be steady in your sannyāsī. That is my request.
