All Vedic knowledge converges on Krishna; even preliminary understanding automatically liberates one from material entanglement.Listen — Srila Prabhupada Uvaca
Prabhupāda: vedādi sakala śāstre kṛṣṇa-mukhya sambandha tāìra jñāne ānuṣaìge yāya māyā-bandha [Cc Madhya 20.144] [In all revealed scriptures, beginning with the Vedas, the central point of attraction is Kṛṣṇa. When complete knowledge of Him is realized, the bondage of māyā, the illusory energy, is automatically broken.] The... Lord Caitanya, summarizing the purport of the Vedic knowledge, He says that vedādi sakala śāstre kṛṣṇa-mukhya sambandha. All the Vedas, all the Vedic literature, all scripture, all over the world, all over the universe—what is meant?
What is the purpose of the scripture? The purpose is to understand Kṛṣṇa. That's all. He is summarizing the whole thing, that "All purposes of different types of scriptures, Vedas, they are meant for realizing what is Kṛṣṇa." That's all.
Tāìra jñāne ānuṣaìge yāya māyā-bandha. Simply by understanding Kṛṣṇa, one becomes automatically liberated from this material entanglement. [coughs] A Kṛṣṇa conscious person hasn't got to make separate endeavor and attempt to become liberated. The more you understand Kṛṣṇa, the more you become liberated, ānuṣaìge, as a by-product. [coughing] [referring to coughing:] Just see how material entanglement, this body.
At any moment, at any moment you can be finished. You cannot be finished, but your all activities is. So therefore we should be very careful, because we have to pull on with this body. Because unless you are perfectly in understanding of Kṛṣṇa, there is no release from this body. It is not that "I want to get release myself from this body; therefore I cut my throat and I get release." No.
That is not possible. You have to be completely detached from this body, and that can be possible when you come..., [coughing] when you understand at least something about Kṛṣṇa. You cannot know Kṛṣṇa completely. That is not possible. He is unlimited.
But even a little knowledge of Kṛṣṇa, preliminary knowledge of Kṛṣṇa, will make you liberated from this material entanglement. Svalpam apy asya dharmasya trāyate mahato bhayāt [Bg 2.40]. [In this endeavor there is no loss or diminution, and a little advancement on this path can protect one from the most dangerous type of fear.] So this Kṛṣṇa consciousness is so valuable that even little progress will make you liberated from this material entanglement. He is citing another nice verse from Padma Purāṇa. There are eighteen Purāṇas.
Out of that, this Padma Purāṇa is one of the most important Purāṇas. vyāmohāya carācarasya jagatas te purāṇāgamās tāṃ tām eva hi devatāṃ paramikāṃ jalpantu kalpāvadhi siddhānte punar eka eva bhagavān viṣṇuḥ samastāgama- vyāpāreṣu vivecana-vyatikaraṃ nīteṣu niścīyate [Cc Madhya 20.145] [There are many types of Vedic literatures and supplementary Purāṇas. In each of them there are particular demigods who are spoken of as the chief demigods. This is just to create an illusion for moving and nonmoving living entities. Let them perpetually engage in such imaginations. However, when one analytically studies all these Vedic literatures collectively, he comes to the conclusion that Lord Viṣṇu is the one and only Supreme Personality of Godhead.] In different Purāṇas... These Purāṇas are made just to complete Vedic knowledge, or supplementary addition to the Vedic literature. Because Vedic literature is very difficult to understand, therefore they have been expanded by the Purāṇas for different classes of men. So there are three divisions of the Purāṇas: sattvika purāṇa, rājasika purāṇa and tamasika purāṇa. Sattvika purāṇa is meant for the higher class of people who are in transcendental knowledge of Brahman, Paramātmā and the Supreme Personality of Godhead.
