Mantak Chia (Chinese: 謝明德, Pinyin: Xiè Míngdé, born April 24, 1944, in Bangkok, Thailand) is a Taoist Master.

Of all his masters, the most influential one was Yi Eng (White Cloud), an eremitic member of the Dragon's Gate sect of the Quanzhen (Complete Perfection) school of Taoism,[2][3] who taught Chia a complete Taoist training system and authorized him to teach and heal.

Later, he studied Western anatomy and medical science for two years to better understand the physiological mechanisms behind healing energy.

Rooted in traditional Taoist practices, Chia's teaching system develops integrated physical, mental and spiritual (energy) bodies internal to human beings.

It emphasizes knowledge and method that are effective to develop the states of inner experience and consciousness that are the birthright of all humans and accessible by all, without unnecessary rituals.

The first step of traditional inner alchemy (Chinese: 內丹) is transforming the material carrier of sexual energy (jing) into qi.

Cultivating the internal body and merging into Tao are the central practices of Taoist inner alchemy, which require great dedication and determination.

[4] Peter B. Clarke thinks that Chia's Healing Tao is one of the few Thai new religious movements to have achieved an international following.
