Eva Wong presents and explains three classic texts that represent the three traditional levels of the Taoist teachings Outer, Inner, and Secret. The Outer teachings are concerned with understanding the Tao as manifested in nature and society. The Inner teachings familiarise the practitioner with the energetic structure of the human body, while the Secret teachings describe the highest level of internal-alchemical transformations within the body and mind for attaining immortality.

She has written and translated many books on Taoism and related topics, including A Master Course in Feng-Shui; Tales of the Taoist Immortals; and Taoism: An Essential Guide.
