The intelligent man is speaking, "My dear Lord, I have served my senses—lust, anger, greediness—so much so. Still, they are not kind upon me. They are still dictating, still dictating, 'Do this, do this, do this, do this.' Therefore," samprataṁ labdha buddhi, " now I have got intelligence by Your grace." Guru-kṛṣṇa-kṛpayā (CC Madhya 19.151). "By the grace of my spiritual master, by the grace of yourself, I have got this intelligence. Now I have come to You, to serve. Kindly engage me." This is surrender. "I have served my senses, lust, greediness and other things so faithfully. They are not satisfied. They still want me to serve. They are not going to give me pension. They want still, 'Oh, what you have done? You have to do so many things.' So now I am disgusted." This is called vairāgya.
Vairāgya. Jñāna-vairāgya-yuktayā (SB 1.2.12). This is required. In human life, this is, this intelligence required, vairāgya, not to serve this material world, but to serve Kṛṣṇa. The Māyāvādī philosophers, they simply stop these material activities. Just like Buddha philosophy, nirvāṇa. He simply advises to stop this. But after stopping, what is, sir? "No, zero. Zero." That cannot be. That is not possible. This is their mistake. But the people to whom Buddha philosophy was preached, they were not so intelligent that there can be better service after giving up this service. Therefore Lord Buddha said, "You stop this service, you become happy, because ultimately everything is zero." Śūnyavādī. Nirviśeṣavādī.
The Māyāvādīs . . . there are two kinds of Māyāvādī: the impersonalists and the voidists. They are all Māyāvādī. So their philosophy is good so far, because a foolish man cannot understand more than this. A foolish man, if he is informed that there is better life in the spiritual world, to become servant of God, Kṛṣṇa, they think, "I became servant of this material world. I have suffered so much. Again servant of Kṛṣṇa? Ohhh . . ." They shudder, "Oh, no, no. This is not good. This is not good." As soon as they hear of service, they think of this service, this nonsense service. They cannot think of that there is service, but there is simply ānanda. One is still more eager to serve Him, Kṛṣṇa. That is spiritual world. That they cannot understand.
So these nirviśeṣavādī, impersonalist, they think like that. Just like a diseased man lying on the bed, and if he is informed that, "When you will be cured, you will be able to eat nicely, you will be able to walk," he thinks that "Again walking? Again eating?" Because he is accustomed to eat bitter medicine and sābudānā, not very palatable, and so many things, passing stool and urine, activities on the bed. So as soon as they inform that, "After being cured there is also passing of stool and urine and eating, but that is very palatable," he cannot understand. He says: "It is something like this."
