What's in it
The Huỳnh Đình Kinh, a Daoist internal-visualisation text that predates much of what later became qigong theory. This is a scan of the 1756 edition.
Hard to read straight through, and the scan quality varies. But it is one of the source documents people keep citing without having seen.
