The forms of practice mentioned here as "complementary courses"
are in themselves high-quality Daoist methods of practice: Tree
Qigong, Daosit Walking, Shui Gong and a daoist sitting
meditation. The Dao Yuan School offers them to people who are
interested in exercises that can provide a very ancient - and
for us, very new - view of nature. As these are advanced
exercise series, at least the practice of Fan Teng Gong at the
Dao Yuan School is required as a prerequisite for entry, and in
some cases prior participation in Edith Guba's energy field.
