There is no doubt that we have been making mistakes on the mental plane, that we have ignored the mind; and this is how we have become sick and unhappy. When we take to the path of Yoga, the most important thing for us is the spirit, then the mind, and then the body. In the materialistic philosophy, body is alpha and omega, but in Yogic philosophy, body is not the first and last. This physical body is not everything; it is just a small portion of our infinite existence. We have to maintain this body correctly, but not through medicines, tranquilizers, and nutritious food alone. We have to supplement right thinking, philosophy, principles, and beliefs. More than that, we have to develop the art of Dhyana Yoga, wherein the eyes are closed, but the mind is expanding and becoming more and more brilliant - more aware. Where this little world of name and form alone is not there - but where the infinite existence is before us in an ever expanding vision of universal life.
