It is easy to learn and enjoyable to practice, and is not a religion, philosophy, or lifestyle. Over six million people have learned it — people of all ages, cultures, and religions — and over 380 published, peer-reviewed research studies have found that the TM technique markedly reduces stress, anxiety, and fatigue, improves learning ability, and promotes balanced functioning of mind and body.
