Indian man (1): I think all the educational institutions are closed for summer vacation. Therefore many students and these people may have come, and these might be scouts, or something like that. I'm not sure, but that is what I guess.
Prabhupāda: They have also manufactured. (laughter) This is going on.
Indian man (1): This shout, that shows they are scouts.
Prabhupāda: 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, physists and many other departmental . . . 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 yogī who is meditating and mind is fully absorbed in Kṛṣṇa consciousness. Otherwise it is material. Material things does not require . . . Maybe a gymnastic, muṣṭika(?) (husti???).
Indian man (1): Not for self.
Prabhupāda: If you practice muṣṭika, naturally you become very stout and strong.
