We have to see how wonderfully the subtle actions are described in Sāṅkhya philosophy by Kapiladeva. There are many modern psychologist, scientist, physist, but they cannot analyze the subtle function that is going on, creating things as they are. Superficially we can see, but how things are taking place, that can be described in the Vedic literatures, not any other book. Therefore it is said, vidyā bhāgavatāvadhiḥ: "One who has studied Śrīmad-Bhāgavatam thoroughly, he has seen the end of knowledge." And actually, Śrīmad-Bhāgavatam is the commentary, or explanation, on the Vedānta-sūtra. Vyāsadeva made Vedānta-sūtra, the ultimate knowledge, and he made his comment also, natural commentary. That is Śrīmad-Bhāgavatam. At the end of every chapter of Śrīmad-Bhāgavatam you will find, brahma-sūtrasya bhāṣya: "It is the natural comment of Brahma-sūtra." So if we study Śrīmad-Bhāgavatam very thoroughly, and specifically from a person bhāgavata, then our life is successful. Nityaṁ bhāgavata-sevayā (SB 1.2.18). That is the instruction, nityam.
Just like here we are having Bhāgavata class. This is not ordinary Bhāgavata class, not jumping over Kṛṣṇa's rāsa-līlā. It is not like that. It is step by step studying what is Kṛṣṇa, what is this material world, what is the sambandha, or relationship with Kṛṣṇa—so many things—how this body has developed, how we have forgotten Kṛṣṇa, how to revive our Kṛṣṇa consciousness. These things must be studied first of all. Then we can understand what is Kṛṣṇa's pastimes with the gopīs. But these professional Bhāgavata preachers, they go, jump over at once. Because it appears like the dealings of young boys and girls, so that is the. . . Here in this material world, sex impulse. . . Here in this material world, sex impulse is the center of all activity. Yan maithunādi-gṛhamedhi-sukhaṁ hi tucchaṁ kaṇḍūyanena karayor iva duḥkha-duḥkham (SB 7.9.45). People are working so hard day and night. What is their happiness? The happiness is sex, that's all. That has been described as tuccham, most abominable.
