|Yoga is a discipline and a way of life, so success is not acquired by merely reading textbooks on Yoga. Nor is success obtained by wearing yoga garments or by anointing oneself with holy markings. Without a sound understanding of the aims of Yoga, the practice of postures and other techniques is not enough. There is no doubt about this.
