Indian man (1): I think all the educational institutions are closed for summer vacation. Therefore many students and these people may have come, and they this cause, or something like that. I'm not sure, but that is what I guess.
Prabhupāda: They have also manufactured. (laughter) This is going on. So Vedic injunction is tad-vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12). Guru is required to understand tad-vijñānam, transcendental science, not for any material understanding. Material understanding, there are so many chemists, (sic:) physists and many other department of... When we speak of guru, it means beyond this material world. For that purpose we require guru. So... Just like now it is being very much advertised that "You execute meditation. Your mind will be strong. Your health will be strong." That means from material point. But keeping your health strong, the medical science is there and so many other thing. But people are taking advantage of this yoga system. The śāstra says that dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ (SB 12.13.1). He is yogi who is meditating and mind is fully absorbed in Kṛṣṇa consciousness. Otherwise it is material. Material things does not require... Maybe a gymnastic, muṣṭika.
Indian man (1): Not for that.
Prabhupāda: If you practice muṣṭika, naturally you become very stout and strong. There are many wrestlers. They have got very strong body. But yoga does not mean that. Yoga means to find out the antaryāmī, Paramātmā, within the core of the heart. Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ (SB 12.13.1). Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). This information we get from the śāstra, that God is also situated within the core of the heart of every living... Sarva-bhūtānām. It is not that God is sitting in the core of the heart of the human being and not in the core of the heart of the dogs. He is there also. But the difference is that the dog cannot find out; man can find out. Therefore he is educated, taught about the yoga system so that constantly he can meditate upon antaryāmī, viṣṇu-mūrti. Perhaps you have seen the picture. We have got that picture. But that is the purpose of yoga, not to make the body strong or the mind very powerful. That is automatically done. Aiye. It does not require separate attempt. Just like if you get one thousand of rupees, ten rupees is already there. Yaṁ labdhvā cāparaṁ lābhaṁ manyate nādhikaṁ tataḥ. If you get Kṛṣṇa, then you get all perfection. Just like Dhruva Mahārāja. Catur-vidhā bhajante mām. Four kinds of men, catur-vidhā, sukṛtinaḥ. If there is piety on the background, not the rascals or sinful man... Therefore śāstra always recommends to be pious, because a pious man has got the future chance of understanding God.
