At an early age, Master Choa became interested in spiritual topics and energy healing. He studied the works of the Rosicrucians, Theosophy, Astara, Huna, Kabbalah, and numerous similar systems.  His formal training as a chemical engineer and his sense of practicality helped him formulate his step-by-step approach to healing that later became the Pranic Healing® system.

For 20 years, Master Choa traveled virtually non-stop, personally instructing students in over 60 countries on 6 continents. Before his passing on March 19, 2007, Master Choa finished 25 books published in more than 30 languages and saw more than 80 Pranic Healing Centers established over in 80 countries over six continents.
