The core concepts of this paper are " The Perfect Integration of Huayan Thinking" and the principles in the medical concept of "The Huayan Sutra". This paper argues for "the shift from contemporary medical treatment to life healing." This also concerns people's behavior patterns, thinking models and language models, viewpoints on disease, pain, medical, treatment, and their interdependence. These are the key issues that connect to the topic of "life healing", which aims at highlighting the viewpoint that medical structure is an important foundation of a healthy society. "Life healing" is a major key to achieve a healthy society. "Healthy lives establish a healthy society, and in reverse, a healthy society supports healthy living." Thus, the value of existence lies in these interactive links, which is the direction that medicine should develop. One may find the foundation of this thought in the Huayan Sutra. Focus of this thesis: 1. The point of departure to relate the Buddhist view on medicine to the modern bio-medical model consists in the teachings of the "Four Noble Truths" and the "Six Sense organs - Six Forms of Consciousness - Six Realms" in Buddhism. 2. Visual Thinking: The employment of visual thinking to the Huayan concept of integration. 3. Evidence from scripture and treatise: (1) Life guide for value principles based on the scripture of the "Huayan Sutra." (2) Life healing inspired by the doctrinal system of the treatises of the Huayan school. The thesis comments with the “Four Noble Truths” as the foundational element and main reference in the Buddhist model of medicine, and proceeds with the presentation of the perfect integration in Huayan thought, which concerns the Huayan doctrine of “dharma-realm as conditioned co-arising” encompassing the aspects of the “ten profound dharma-gateways,” the “perfect integration of the six characteristics,” and the “inseparability of all from one, and one from all.” The key point consists in introducing a holistic approach to medical and therapeutic methods which involves the dynamic change of perspectives during diagnosis and therapy situations. I argue that, for this purpose, ideas and thoughts developed in the doctrinal framework of the Huayan school might provide a source of inspiration, and perhaps a prospect for the ideal of a healthy society.
