本文以聖嚴法師的《觀音妙智》講要為主要研究對象，探討聖嚴法師對《楞嚴經》耳根圓通的詮釋，嘗試耙梳出其觀音思想的核心。在論述架構上安排：一、前言；二、由聖嚴法師年少時的情境與背景入手，帶出觀音信仰是法師的安身立命處；三、就《楞嚴經》文獻上的真偽問題，說明聖嚴法師所抱持的態度；四、解析耳根圓通的字面的意思，進而整理經文界說耳根圓通的四種特色；五、首先略述《楞嚴經》耳根圓通的教授者與實踐者，其次著重耳根圓通在《楞嚴經》中所扮演的角色，最後論陳耳根圓通的基本理念架構；六、探討耳根圓通的修證實踐核心；七、收尾之前整理祖師們與聖嚴法師針對耳根圓通的應用；八、結語與展望。經由本文的鑽研，不僅可以一窺《楞嚴經》耳根圓通的全貌，而且透過聖嚴法師精闢地解析耳根圓通法門的內涵，開啟吾人觀音信仰、理論、實踐的視野。

This paper examines Master Sheng Yen’s work, Wondrous Wisdom of Avalokiteśvara (Guanyin miaozhi ), focusing specifically on his understanding of the essential thought of the“perfect penetration method of the faculty of ears” (ergen yuantong ) section of the Śūra gama Sūtra . The structure of my examination is eightfold: 1) Introduction; 2) Showing how this method of contemplation and Guanyin devotion formed the core of Master Sheng Yen’s own practice by examining his youthful years; 3) Discussion of the apocryphal nature of the Śūra gama Sūtra and Master Sheng Yen’s position on this matter; 4) Providing an etymological analysis of “perfect penetration method of the faculty of ears”(ergen yuantong ) and an in-depth analysis of four distinct characteristics of this contemplation method; 5) Discussing the transmitter and practitioners of this method and the doctrinal position and structure of this method in the Śūra gama Sūtra ; 6) Exploring the essence of the practice of perfect penetration through the ear faculty that one can cultivate and actualize; 7) Organizing all applications of this practice made by ancestral masters and Master Sheng Yen; 8) Conclusion. This paper reveals not only a complete picture of the “perfect penetration method of the faculty of ears,” it also provides an overview of Master Sheng Yen’s insights into the method’s contents, theories, devotional dimensions, and stages of actualization.
