More and more people are practicing yoga to do something good for their soul and body. However, yoga is not a competitive sport, and both the headstand and the sun salutation require patience and calmness. Otherwise, yoga can have catastrophic effects, leading not to enlightenment but straight to imaging tests like X-rays or MRIs. KATA-YOGA demonstrates how not to practice yoga: Eva Haak, a yoga teacher for over a decade after a four-year training, presents twelve popular asanas in humorous texts and witty illustrations that can be physically risky and easily turn into disaster asanas if performed too early, too frequently, or too ambitiously, and without the guidance of attentive yoga instructors. Eva Haak encourages a carefree questioning of practices, trying out alternatives, and practicing in a relaxed manner.
