Essence of Vedic literature—Śrīmad-Bhāgavatam. Nigama-kalpa-taror galitaṁ phalam (SB 1.1.3). It is recommended that nigama means Vedas. Nigama is compared with a tree. Nigama-kalpa-taru. Kalpa-taru means desire tree. From the Vedas you can take all kinds of education, knowledge. Therefore it is called kalpa-taru. So as of the tree there are fruits and ripened fruit . . . just like mango tree. There are fruits, green mango and ripened mango. The ripened mango is very interesting. So Śrīmad-Bhāgavatam is the ripened mango of the desire tree of Vedic knowledge. Nigama-kalpa-taror galitaṁ phalaṁ śuka-mukhāt. And everyone knows that the . . . if the ripe fruit in the tree is tasted by the parrot, it becomes twice tasteful. So Śukadeva Gosvāmī, śuka-pakṣī. Śuka means parrot. He's speaking. Śuka-mukhād amṛta-drava-saṁyutam, pibata bhuvi bhāvukāḥ rasam ālayam (SB 1.1.3). These are the recommendation. So people are not interested. It is a great regret, matter of regret, that in India, where these literatures are available, where the sages and saintly persons left for us such nice literature, vidyā-bhāgavatāvadhi, the limit of all education, Śrīmad-Bhāgavatam, they are not interested. They are interested in some other, Marx literatures, Karl Marx literature, not Bhāgavatam. This is the India's misfortune.
So anyway, if somebody's interested, it is his fortune, because such kind of instruction as they are available in the Śrīmad-Bhāgavatam or Bhagavad-gītā, they are apavarga-vardhanam, apavarga-vardhanam. Niśamya puṁsām avaparga-vardhanam. Puṁsām, for the people in general. Apavarga-vardhanam, dhiyā . . . dhiyā abhinandya. When actually a person advanced in spiritual knowledge, somebody comes to him to enquire . . . because it is the system. Tad viddhi praṇipātena paripraśnena sevayā (BG 4.34). Tad-vijñānārthaṁ gurum evābhigacchet (MU 1.2.12). This is the instruction. So when a person comes to a transcendentalist to inquire about śreya uttamam—uttamam means transcendental subject matter—he becomes very happy. He becomes very happy. One who hears very attentively about the spiritual subject matter, the spiritual master becomes very happy. So Kapiladeva became very happy by seeing His mother so eager to understand about the spiritual subject matter. Therefore, dhiyā abhinandya, thanked her, "O My dear mother, thank you very much. You are so interested in the subject matter." Because people are not interested. But when He saw that the family, head of the family, His mother, was interested, He became very happy, and therefore abhinandya, thanked her, "Yes, thank you, mother." Why? Now, ātmavatāṁ satāṁ gatiḥ: "You are asking the subject matter to know from Me which is approved by the ātmavatām."
Ātmavatām means self-realized person. Self-realized . . . without self-realized person, nobody can inquire about uttamam, śreya uttamam. Everyone is interested the immediate pleasing things. Immediate pleasing things. "I want to taste something which is very tasteful to my tongue. Never mind whether it is not eatable or eatable . . ." Just like hogs and pigs, they have got a taste to eat stool, and they like it. They like it, immediately. Everyone have, I think, in India, they have got experience. When they go to pass stool in the field, the hog is waiting to taste. They are so much addicted. Similarly, we have become to taste anything and everything, like hog. There is no discrimination. There is no restriction. Because they have no tapasya. Tapasya, when you are engaged . . . and this subject matter, spiritual realization, means tapasya. Tapasya. But it has been made easy by Caitanya Mahāprabhu. Very easy. Ceto-darpaṇa-mārjanaṁ bhava-mahā-dāvāgni-nirvāpaṇam, paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam (CC Antya 20.12). Little tapasya. Just spare little time and chant Hare Kṛṣṇa. This much tapasya, we are not ready. Etādṛśī tava kṛpā bhagavan mamāpi durdaivam īdṛśam ihājani nānurāgaḥ. Kṛṣṇa is more interested to get us in the apavarga-vartmani, in the path of liberation. And He has given very simple method: chant Hare Kṛṣṇa. Harer nāma harer nāma harer nāmaiva kevalam (CC Adi 17.21). Still . . . nāmnām akāri bahudhā nija-sarva-śaktis tatrārpitā niyamitaḥ smaraṇe na kālaḥ. And to practice this chanting of Hare Kṛṣṇa, there is no hard-and-fast rule. Niyamitaḥ smaraṇe na kālaḥ. Any time suitable you can chant, and you get perfection. Paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam. This much little trouble, austerity, or whatever you call. But we have no interest. Being contaminated by this material . . . this Kali-yuga . . . etādṛśī tava kṛpā bhagavan mamāpi durdaivam, misfortune, durdaivam īdṛśam ihājani nānurāgaḥ. "I have no attraction."
So therefore Kapiladeva or His representative, when he sees somebody is little interested, he becomes very glad and thanks him, "Thank you very much." Because people are not interested. So Kapiladeva, when He saw His mother interested, He thanked within. Not openly, but within the mind, "Thank you, mother. You are so interested." So dhiyā abhinandya ātmavatāṁ satāṁ gatiḥ. The process, the questions which she put, that is ātmavatāṁ satām. Not ordinary persons. Satāṁ prasaṅgān mama vīrya-saṁvido bhavanti hṛt-karṇa-rasāyanāḥ kathāḥ (SB 3.25.25). Kṛṣṇa-kathā becomes interesting in the association of satām ātmavatām, those who are interested in self-realization, those who are devotees.
