Those who are very much addicted to the bodily necessities of life, for them this haṭha-yoga system . . . haṭha-yoga system means yama, niyama, aṣṭāṅga-yoga. It is called aṣṭāṅga-yoga. Yama, niyama, āsana, prāṇāyāma, dhyāna, dhāraṇā, pratyāhāra, samādhi. These things are in the aṣṭāṅga-yoga. The first thing is yama-niyama. One must have regulated life. That is called yama-niyama. Then practice āsana. There is mechanical process of sitting which will help you, concentration of the mind, āsana. Then praṇāyāma, concentration of the mind. Then meditation.
So 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.
