Falun Dafa (aka Falun Gong) practice is not complicated. The five gentle exercises, one of which is a meditation, are easy to learn, enjoyable, and at the same time both relaxing and energizing. Here is a 3 minute video demo of the exercises: YouTube

The teachings of Falun Dafa are included in the book Zhuan Falun. Falun Dafa was introduced to public in China in 1992 by Teacher Li Hongzhi. During the next couple of years, Teacher Li was traveling around the country and giving public lectures teaching Falun Gong (it was a typical way for many other qigong masters in China to teach their qigong practices). The book "Zhuan Falun" was published in December 1994. It has nine chapters based on Teacher Li's nine-day public lectures. Many people who had no chance to attend Teacher Li's lectures learned the principles of Falun Dafa from the book or recording of the lectures. Key contents of the book include discussion of: the origins of qigong and the long-forgotten meaning of cultivation; the roots of illness, and their fundamental removal; karma: its origin, effects, and transformation into virtue; Falun Gong's relation to qigong, Buddhism, Taoism, and other cultivation methods; the meaning and function of supernormal abilities; the question of eating meat and the issue of attachments; genuine, integrated cultivation of mind and body; the concepts of Enlightenment and Consummation. The book can be found online and it has been translated into more than 30 languages. The official website is at falundafa.org

The principle of Falun Dafa is Truthfulness, Benevolence, and Forbearance.
