This is very important point. The process of understanding knowledge. The modern tendency is to understand by dint of one's sense perception. That is not possible. There are many things, especially spiritual matters; nobody can understand by simple speculation. So one has to accept the authority. So according to Vedic culture, the Vedas are the authority. If there is some information in the Vedas, you accept it, authority. That is very nice system.
Just like a child. If he wants to understand something out of his own intelligence, it is very difficult to understand, but if he asks his parents, "Mother, what is this?" mother says, "My dear child, this is this." So he understands immediately, "Oh." Because mother is the authority. Mother will not cheat the child. Similarly, those who are liberated persons... Vedas means the knowledge given by the liberated person, by God. So if you accept it, then you get the knowledge immediately. You haven't got to make research or philosophical speculation.
That process is deductive process. That process is very nice. So Vedic process means, as it is stated in the Fourth Chapter, that evaṁ paramparā-prāptam (BG 4.2), by disciplic succession, if you try to understand the truth, then you get infallible knowledge. Your purpose is to get knowledge. As soon as you get the knowledge from authority, your knowledge is perfect. But if you want to get the knowledge by your own sense perception, you will never be able to come to the right conclusion; neither it is possible to get knowledge in that process.
