The first one is the discussion class, including preface to the infinite taiji diagram, analogy of the same origin of three religions, and graph theory, with a total of 35 chapters. The second category is question and answer, including asking about 80 questions about life at that time and more than 40 questions about Tai Chi. The third category is poetry, including 66 poems by Dan at that time, 30 cases of Zen and about 300 miscellaneous poems. The fourth category is exhortation, including persuading parents to be ten times grateful and change people's lives. The whole book aims to combine the three religions and Wan Qi law. It is said that the doctrine of the mean, truth and eternity are the extremes of the three religions, and they all refer to the hard-won wisdom through the ages. Confucianism, Buddhism and Taoism "share the same path of Tai Chi, stand at home and abroad, and all take education as their heart." The author advocates the theory of heaven with the unity of three religions, which is based on the double cultivation of life. It is called "Tai Chi" to think that "infinity" is pure reason, and there is chaos after rationality. Taiji gives birth to three talents, establishes everything, takes reason as the foundation of life, and "there is no end to doing three talents". I also know that infinity is "the truth of Taiji" and Taiji is "the wonder of infinity". True inaction is the beginning of human nature, and a wonderful life is the beginning. Tao is based on inaction, usefulness, unity of body and use, interdependence of reason and action, and changing Tao. Also known as two examples of joint life. Sexism is based on purity and silence, and abstinence and wisdom are the first meanings; Life is natural by doing nothing, and spirit is the first meaning. However, abstinence, determination, wisdom, essence, qi and spirit are inseparable. "Abstinence, determination and wisdom"; "Discipline, determination and wisdom are based on essence, qi and spirit, and essence and spirit are based on discipline and wisdom." So a monk has to live two lives. In the book, I also talked about practicing elixir of life and paying attention to physical and mental peace. It is believed that "six quiet and clear squares are true elixirs." There are two kinds of Dan method: gradual method is based on saving the gods and nourishing the people, sudden method is based on purity and nothingness, and sudden method is based on Quan, which is similar to stone. The book strongly advocates that Buddhism and Taoism are the same, "the Buddha nature is the same as the elixir"; "Immortality, immortality of Buddhism, death is for clay pills." . In short, the integration of the three religions, the integration of reason and practice, the dual cultivation of life, and the equal emphasis on abstinence, determination, wisdom, essence, qi and spirit are the main arguments of this book.
