The purpose of the Wudang Longevity Qigong practice is the stimulation of Qi around the Heavenly Orbit or Micro Cosmic Obit.
Daoist Priest Grand Master Zhong Yunlong taught the Wudang Longevity practice to me in September 1999 at Wudang Mountain or Wudangshan in China and has given me the authority to share its healing benefits. It is best practiced outdoors, looking into the distance.
