Prabhupāda:
- taijasānīndriyāṇy eva
- kriyā-jñāna-vibhāgaśaḥ
- prāṇasya hi kriyā-śaktir
- buddher vijñāna-śaktitā

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. Yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham. Ataḥ gṛha-kṣetra-sutāpta-vittair janasya moho 'yam ahaṁ mameti (SB 5.5.8).
So we are not aware what is the aim of life. So Kṛṣṇa is very kind. He therefore comes. He came just before the beginning of this Kali-yuga, the most fallen age, and left for us the Bhagavad-gītā. And then, after Him, after His departure... It is said in the Śrīmad-Bhāgavatam, "After departure of Kṛṣṇa from this planet to His own abode, the principle of religion and knowledge, where it is kept?" So the answer is, "It is kept in the Śrīmad-Bhāgavatam." Adhunā udita. So Kṛṣṇa is nondifferent from Bhagavad-gītā as it is spoken by Him personally, and He is also represented by Śrīmad-Bhāgavatam, sound representation. So we should take the advantage of Bhagavad-gītā and Śrīmad-Bhāgavatam. They are kṛṣṇa-kathā, kṛṣṇa-kathā. Kṛṣṇa-kathā means news or words about Kṛṣṇa, or Kṛṣṇa's kathā, the words given by Kṛṣṇa. That is Bhagavad-gītā, kṛṣṇa-kathā, Kṛṣṇa's words. And Śrīmad-Bhāgavatam means words for Kṛṣṇa. Both of them are kṛṣṇa-kathā, or kṛṣṇa-upadeśa, instruction by Kṛṣṇa.
So here is... Kapiladeva is giving instruction, how things have developed one after another from Kṛṣṇa, from Kapiladeva. Kapiladeva and Kṛṣṇa, there is no difference. You read the purport.
