Yoga system is very difficult this time, haṭha-yoga system. But we do not know that. We want everything very cheap. Oh, that is not possible. Because it is not possible, therefore in this age the śāstra recommends, harer nāma harer nāma harer nāmaiva kevalam (CC Adi 17.21). Simply chant Hare Kṛṣṇa mantra and you will achieve . . . and see the result. We have got thousands of students. They have been called by the newspaper reporter "bright-faced." Compare with these students and any yoga class student: how much they know, how do they know?
So this haṭha-yoga system is a recommended system. That's all right. But it is not possible in this age. It is very difficult. This practice is very easy. Even a child can chant Hare Kṛṣṇa, and he becomes purified. Ceto-darpaṇa-mārjanam (CC Antya 20.12). So if your business is how to become purified and realize yourself or realize God, then this is the system in this age. You have to take to it, Kṛṣṇa consciousness. If you take to other system, you are at liberty. But so far śāstra is concerned, that will not be successful.
Yes?
Guest (2): When the living entity comes to the material world, what is the state of the spiritual body? And how does this spiritual body begin to develop?
Prabhupāda: Spiritual body is there already. You simply cover yourself with another material coating. Just like you are trying to go to the moon planet. Your body's there, but you coat your body just suitable to the moon planet. And that dress costs $40,000, or something like that. (laughter) So after spending $40,000 for each man and going for so many years, they have collected little dust. That is their success. So if you want to waste your money in that way, do that. (laughter)
Yes?
Indian lady: Is it better to chant the Hare Kṛṣṇa mantra loud or is it better to hide the mantra?
Prabhupāda: As loud as possible.
Devotees: Jaya! Haribol!
Prabhupāda: So that others can hear and take benefit of it. There is no secret. It is not that secret mantra, that "I'll give you a special mantra, and you give me $35." (laughter) It is open to everyone. Chant loud, as loudly as possible. No question of payment.
