Founder of Modern Pranic Healing and Arhatic Yoga, Grand Master Choa Kok Sui is credited with the development of an energy healing system using prana or ki more effectively and efficiently. Prana or ki is the life force that keeps the body alive. Trained as a Chemical Engineer and a successful businessman, he spent more than 30 years researching and studying literature and books on esoteric sciences, examining and sorting through their various healing techniques, and eventually developing the concepts, principles, techniques, and practical applications of Pranic Healing as it is widely known today.
