The founder of the White Willow School of Tai Chi has created this rich parable to introduce the spiritual teachings of his Tai Chi lineage. It concerns a 13th-century Taoist monk named Hunglu who finds peace and serenity in his monastic existence until one day the mysterious Butterfly Immortal appears to him. The time has come for him to leave the dreams and meditations of the Yin world behind and explore the physical and human realities of the Yang world.
