Practically the whole population of India, they are dedicated to spiritual life. Perhaps you may not know, but anyone who has taken birth in India, he has got a natural inheritance of spiritual life. Unfortunately, at the present moment the leaders are under wrong impression that in India, being too much spiritually inclined, its material advancement has been checked.
But material advancement does not become hampered by spiritual knowledge. That is a wrong impression. Rather, if you become spiritually advanced, your material necessities will be very nicely adjusted. That is the injunction, Bhagavad-gītā, yuktāhāra-vihārasya yogo bhavati siddhi-hā (BG 6.17). Yoga. Spiritual life means yoga. So yogic life can be very nicely successful if you adjust your material necessities of life. If you become extravagant so far your material necessities of life is concerned, then you cannot make successful in yogic life.
So there are so many rules and regulations. Those who are interested in yoga, you will find in the authorized books, yoga indriya-saṁyamaḥ: "The aim of yogic power, yogic success, is to control the senses." Our senses in this material world have been described as venomous serpents. Indriya-kāla-sarpa-paṭala. Kāla-sarpa, cobra, black cobra. So these indriyas are like that. Indriya means senses. As soon as touches, immediately it makes him poisonous. And that is the cause of our material conditional life. The more we are indulging unrestrictedly in sense gratification, we are becoming more and more entangled.
