స్వామి శివానంద సూక్తి

Body-building is the foundation of nation building. Build the body through nature’s aids. Avail yourself of healing agencies of nature—the sun, water, air, earth, steam, fasting, herbs, etc. Observe the laws of eating, drinking, sleeping, thinking and conducting yourself as laid down by the ancient Rishis and sages. Live in tune with nature. Use the herbs and greens. He who observes the rules of health and hygiene, who is moderate in eating, drinking, and other things, regular in his prayer, Japa, meditation who is free from jealousy, pride, hatred, who observes Brahmacharya, is free from diseases. He is healthy and attains longevity.
