WILD GOOSE QIGONG
Wild Goose Qigong is an 1800 year old skill that was developed by Daoist monk Si "Dao An", in the Kunlun Mountain Range on the edge of Western China and Tibet during the Jin Dynasty. Dao An, along with other Daoist monks observed the Da (Big) Yan (Wild Geese) who were regarded birds of longevity and unity.
From these observations
Wild Goose Qigong (also called Dayan Qigong) began to be developed based upon the movements that the monks observed in these beautiful birds. They also combined the skill with their knowledge of Chinese medicine theory which included knowledge about the channels and acupoints in the body. Wild Goose Qigong is the foundation form of this Qigong system but many other forms followed until eventually there were at least 72 forms and methods. Daoism uses a lot of numbers and each number has a special meaning and connection. Some relate to the Yijing (Book of Changes), some to the stars and constellations in the sky and some to the Bagua. There is more information on this in Michael Tse's Wild Goose Qigong books.
Not all of the Kunlun Dayan Qigong forms are long forms like the Wild Goose Qigong. Some are shorter forms, like Eight Pulling Waist Gong or Seven Star Opening Gong. Some of the skills are different meditations and some are healing skills. In addition, Master Tse has continued to develop other Qigong forms, such as Balancing Gong and Healthy Living Gong, based upon the principles of the Kunlun Dayan System.
