Nine Solarian Charts of Inner Alchemy

This book records diagrammatic instructions for Internal Alchemy cultivation, with a total of nineteen diagrams, divided into three parts: The first part consists of diagrams themed "Inner Cultivation of the Yin Soul, Outer Refinement of the Yang Spirit", each with human figures illustrating the skills of guiding qi to rise, fall, float and sink, as well as the method of inner visualization through the condensation of divine radiance. The second part features diagrams combining the Eight Trigrams with lunar phases, teaching practitioners that "the divine power operates and transforms in an endless cycle; the Eight Trigrams are arranged in order, adhering to proper application without deviation". The third part is The Supreme Mysterious Nine-Yang Diagram for Immortal Cultivation, symbolizing the state of a cultivator who "eliminates all pure yin and gathers the divine fire of the nine yangs" and achieves spiritual liberation to attain the true Dao.

At the end of the book is an attached The Supreme Mysterious Ode to the Twelve Two-Hour Periods, which explains the cultivation phenomena corresponding to each of the twelve earthly branches in a day.
