Meditation is not so easy thing. Unless you practice the preliminary necessities of meditation, you cannot concentrate. Even if you sit down closing your eyes, either you will sleep or you will think of other things which are more important, you think, more important in your life. So the yoga system is practically not very helpful. Helpful means we cannot execute this system very nicely.
So this paramparā system, the subject I was discussing, that how I become the representative of Kṛṣṇa, it is not very difficult. Everyone can become a representative of Kṛṣṇa, provided he exactly presents what Kṛṣṇa says. That's all. Just like a peon: he is also representative of the postal department, ordinary peon. How he becomes representative of the whole postal system? If he delivers your letter or money order without mishandling it, as it is. You have . . . some friend has sent you some money order. He gives you the paper, you sign, and he pays you. But if he pilfers the method, then he is no longer representative. He becomes thief, rogue.
So representative of Kṛṣṇa is also in the same way. If you present Kṛṣṇa's word as it is, without pilfering, without any adulteration, then you become Kṛṣṇa's representative. There is no difficulty. But, unfortunately, people want to show their scholarship that, "I understand Bhagavad-gītā from this angle of vision." Why should you try to understand Bhagavad-gītā from a different angle of vision? The first preference should be given to the author.
