With advanced medical technology and with various encounters in life, it is even more necessary to clarify one's own beliefs and values so that one can live out a life of significance and quality due to the forethought to evaluate choices and make decisions. Since Taiwan's Patient Autonomy Law was formally implemented on January 16, 2019, relevant medical institutions have also provided consultations regarding pre-established medical care for people who want to sign a medical autonomy decision. When receiving medical care consultations from medical professionals, people also have to think about philosophical practices in hospitals and use philosophical counseling to help themselves cope with the reality of being ill and think about choices of medical treatment and caring. Beginning with the life dilemma, illness, troubles, and spiritual encounters at the end of life that are represented in the Gandavyūhasūtra, this article intends to explore the methods and resources that Buddhist philosophical counseling in the Gandavyūhasūtra can provide for the patient's autonomy and consultation. In addition to the preface and conclusion, this article is divided into five parts in order to propose an experimental construction: Part One reviews the cases of life encounter in the Gandavyūhasūtra, drawing attention to retrospective reflections on life; Part Two discusses the considerate healing presented in the Gandavyūhasūtra, focusing on the caring relationships of philosophical counseling; Part Three concerns spiritual consultations of physical illness by examining the therapeutic approaches shown in the Gandavyūhasūtra; Part Four explores the Bodhisattva medicine of the Gandavyūhasūtra, especially the spiritual caring of worries and anxieties; Part Five investigates the spiritual company and support of hospice care in the Gandavyūhasūtra.
