It is very difficult to, I mean to say, assimilate the Vedic instruction. But if one has got unflinching faith in Kṛṣṇa and guru, the Vedic knowledge automatically becomes revealed. This is the system. Then you can understand. Just like big, big scholar, big, big leaders. Take for example our big political leader, Gandhi. He says that "I don’t believe that there was any person ever living as Kṛṣṇa." He said that. Just see. Such a big leader, and he is known to be very pious man, but he could not understand Kṛṣṇa. Although he was lecturing on Bhagavad-gītā, and people knew that Gandhi's life and soul is Bhagavad-gītā, but the result is that he does not understand Kṛṣṇa. Just see.
So you cannot enter into the Vedic literature unless you go to the paramparā system. It will remain always blocked. This is one example of a big politician. And big scholar, Dr. Radhakrishnan, he, while commenting on the verse man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65), he says that it is not to Kṛṣṇa the person. Just see. He's a big scholar. He is known as a very big scholar, philosopher—he also does not understand Kṛṣṇa. And Bhagavad-gītā means Kṛṣṇa. Kṛṣṇa is speaking. But these people do not understand what is Kṛṣṇa. Then what will they speak? This is going on all over the world—in the Western world and in the Eastern world. So you cannot understand the Vedic literature unless you understand through the paramparā system. You may be very big man, you may be very big scholar, but the meaning or the purpose of the Bhagavad-gītā will be sealed.
