So the Bhāgavata says, simply to understand "This is not Brahman, this is māyā, this is not Brahman," if you go on speculating and without any interest for devotional service or Kṛṣṇa consciousness, then teṣām eṣa kleśala eva śiṣyate. So their advancement in self-realization is simply troublesome. Troublesome. They simply take the trouble of discriminating that "This is māyā, this is Brahman. This is false, this is reality." Because they have no other engagement. For a devotee there are so many engagements, but the Māyāvādī philosopher takes it for granted that these devotees' activities... "They are cooking for Kṛṣṇa or they are offering prasādam to Kṛṣṇa, they are decorating Kṛṣṇa, or they are singing for Kṛṣṇa, glorifying Kṛṣṇa—these are all mayic activities," they say. Because this bhakti-mārga is not appealing to them. They simply want to... Similarly, the bhaktas also say that "You are simply wasting time. Real thing is Kṛṣṇa. Just engage yourself in the service of Kṛṣṇa." They also say, "Kṛṣṇa is also māyā." According to them, Kṛṣṇa is also māyā. And Kṛṣṇa in Bhagavad-gītā says that they are fools. How? Avajānanti māṁ mūḍhā. Mūḍha means "The fools, they minimize Me. They decry at Me." Avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritaḥ (BG 9.11). "Because I come as incarnation, therefore the fools, they consider..., or they deride at Me." Paraṁ bhāvam ajānanto. They do not know the background of the Supreme Personality of Godhead. Mama bhūta-maheśvaram. Kṛṣṇa says, "I am the Supreme Lord." They do not know. Who do not know? The Māyāvādīs, they do not know. So therefore their labor of love for discriminating what is māyā and what is not māyā is simply troublesome. Teṣām kleśala eva avaśiṣyate nānyad yathā sthūla-tuṣāvaghātinām. Just like the skins of rice, when it is taken, there is no more grain. So the grain is separated from the skin by beating. There is a beating machine in India. That is a crude, original way of separating the grain from the skin. So when the skin is out from the grain, if you simply beat the skin, no more there is grain. So similarly, if you make minus Kṛṣṇa, then the study of Bhagavad-gītā is simply waste of time and labor of love. That's all. "Not Kṛṣṇa." This means, this Māyāvāda philosophy means simply taking trouble. Bhagavad-gītā is all full..., simply Kṛṣṇa. To understand this, it is a science of Kṛṣṇa. And if somebody says, "It is not Kṛṣṇa," then what is that? Simply waste of time and labor. The same thing: the grain is taken out. Simply the skin, enjoy the skin. What is there in the skin?
So this is the verdict of Śrīmad-Bhāgavatam, that śreyaḥ-sṛtiṁ bhaktim udasya te vibho kliśyanti ye kevala-bodha-labdhaye. Bodha-labdhaye. They stress on knowledge. What is this knowledge? You can talk on any insignificant thing for many years. That is not knowledge. Just like in the present modern civlization, so many nonsense articles without any utility, or volumes of volumes of books are sold in the market. There is nothing, no substance. Take for this..., newspaper. Especially in your country, volumes of papers in the news. Just after glancing over, it is thrown away. That's all. No more use. Just as The newspaper is published early in the morning, and just in the afternoon it is useless, it is heap of paper only, because there is no substance. Nobody can take any interest. But see Bhagavad-gītā, it is, five thousand years before it was published, and a few pages only, and how much care is being taken after Bhagavad-gītā. Because there is substance. Similarly, if you don't accept the substance, simply if you are busy with the skin... In Bengali it is called cavara nie tanake (?). Cavara means skin. You have seen coconut. The coconut is covered by heavy, what is called, fibers. So if you give up the coconut and simply quarrel with the fibers, what profit is there? There is no profit. Similarly, if you give up God, or Kṛṣṇa, who is the essence of everything, and you make your advancement in scientific knowledge, in physics and chemistry and so many departments of knowledge, so according to Bhāgavata this is simply waste of time. Simply waste of time. But what we'll gain? Kevala-bodha-labdhaye. Suppose you understand in your human form of life the whole constitution of the universe... That is stated in Bible also, that "If somebody understands everything, but not God, then what does he gain?" Similarly, there is another verse in Śrīmad-Bhāgavatam that one may be very much expert to count even the atoms of the universe. You smash the universe and grind it into powder, and you just count all the atoms. That is possible . But still, it is not possible to understand the Supreme Personality of Godhead. Therefore who understands the Supreme Personality of Godhead, he understands everything. Tasmin vijñāte sarvam evaṁ vijñātaṁ bhavanti. If somebody understand the Supreme Absolute Truth, Personality of Godhead, he understands everything because He is everything.
