“Medicine Buddha Sutra” is a Mahayana Buddhist classic in the middle and late period. Its Buddhist ideas and beliefs began to prevail in the Han Dynasty during the Jin and Song Dynasties. During the Sui and Tang dynasties, its transmission reached a climax, and then it returned to the people. It has always played an important role and influence in beliefs, thoughts and culture. The Book of Medicine has a unique and profound Buddhist thought. The realm of life is the goal that we must pursue throughout our lives. Based on the inductive analysis of the twelve major vows made by the Medicine Buddha in the Book of Medicine, the thesis divides happiness into inner happiness, outer happiness and transcendent happiness. "Right knowledge and right view" and physical health and happiness are very important factors. The second chapter starts from the vows made by Medicine Buddha, from the chapters on the purity of morality, the fulfillment of all faculties, the recovery of evil and the righteousness and the acquisition of wonderful food. From the chapter on inner peace Undisturbed and contented as a foothold, proceed outward in pursuit of another level of happiness. The third chapter focuses on the enlightenment of career, endless wealth, physical and mental well-being, and the acquisition of wonderful clothes, in order to explore the prosperity and happiness of this world and cut into the essence of humanistic Buddhism. A woman becomes a man and liberates herself from sorrow and suffering to explore her birth happiness. Happiness is to develop one's inner self, not to seek outside. From the connotation of the Medicine Master Sutra, it can be summarized and combed. Although life is not as good as nine out of ten, it is necessary to learn Buddhism, change oneself and do it (self-interest), imitate the Buddha and Bodhisattva's wish to save the world and practice Buddha, so that others can also obtain benefits and joy ( Benefit people) and continue to practice diligently, relieve the afflictions and torture (transcendence) of physical and mental illness, purify one's own mind and human heart, and practice the human concept of the Pure Land of the Lazuli Buddha Kingdom.
