Zhuan Falun, contains the core of Falun Dafa's teachings and is written at a higher level than Falun Gong. It is an exploration of the key concepts of Falun Gong, focusing on the concepts of truthfulness, compassion, and forbearance. Among the topics covered are the origins of qigong and the long-forgotten meaning of self-cultivation, and the roots of illness and why we fall ill or have tribulations and the fundamental Falun Gong method of dealing with it. Experienced practitioners of Falun Dafa read this book regularly to refresh their understandings of the practice's teachings and stay grounded in their cultivation.
It is recommended that new learners start with Falun Gong before moving on to Zhuan Falun, and to read each book continuously, starting from where you stopped, not leaving out anything, for best results.
