It was originally a nomadic system and uses nature and the elements weaved into the practices. The Burning Palm (not to be confused to 'Imprint Palm' or other palm conditioning and cultivation methods) became the Chinese character for fire "Fo" Fo Jeung. It has been translated to Burning Palm in English due to the sensation caused by the strikes when hit for healing or martial application. There are also signs and results from the training that signify certain levels of development and at this level, the practitioner will understand the reference to 'burning'.
Burning Palm is not a method like Iron Palm but a dynamic system or warrior path that frees the mind, body, spirit and unifies them enabling the practitioner to become a healer rather than just having the ability to heal. It connects you to the infinite all that is.
