Devotee: "Yoga practice is not meant for attaining any kind of material facility. It is to enable the cessation of all material existence."
Prabhupāda: So long you require some material facilities, you'll get material facilities, but that is not solution of the problems of your life. Material facilities, I think you American boys and girls, you have got material facilities better than any other nation. At least better than India, that I can say by my experience. And I have traveled in so many countries, in Japan also I have seen, but still you are better positioned. But do you think you have attained peace? Can anyone of you say, "Yes, I am completely in peace." Then why the youngsters are so much frustrated and confused? So, so long we shall utilize the yoga practice, this practice, for some material facilities, there is no question of peace. Yoga practice should be performed to understand Kṛṣṇa, that's all. Or to make your lost relationship with Kṛṣṇa reestablished. That is yoga practice.
