星雲大師四無思想的理論與實踐，是大師將佛法運用在日常生活的體現，這中間融攝《金剛經》的離相思想，大師一生奉行「以無為有，以退為進，以眾為我，以空為樂」的人生觀。落實在生活的實踐就是《金剛經》以無的思想所開演的佛法生活，大師所提出的四個無，「無相布施、無我度生、無住生活、無得而修」是《金剛經》的核心法要。 本研究分析四無的理論來自大師對《金剛經》的詮釋，是大師將《金剛經》的四相轉化成現代的語言，並延伸出佛法的真實義。即：無相布施有無限的功德、無我度生有無上的慈悲、無住生活有真正的自在、無得而修有真實的獲得，這與大師說，以出世的精神做入世的事業，理念是相同的，出世的精神就是空，入世的事業就是有，是大師「以無為有」作為度眾的事業。並從此理念開展大師一生對四無的實踐。 The theory and practice of Venerable Master Hsing Yun's “Four Insights of Emptiness” is a manifestation of his application of Buddhism to daily life, which incorporates the idea of going beyond notions in the Diamond Sūtra. Throughout his life, Venerable Master Hsing Yun practiced his life perspective of viewing “nothing as something, retreat as progress, the multitude as the self, and emptiness as happiness.” The practical actualization in his life is this Buddhist lifestyle which expands from the emptiness doctrine in the Diamond Sūtra; the four principles proposed by Venerable Master Hsing Yun, “to give without notions, to liberate with no notion of self, to live without abiding, and to cultivate without attainment,” are the core teachings of the Diamond Sūtra. The author's analysis of the “Four Insights of Emptiness” comes from Venerable Master Hsing Yun's interpretation of the Diamond Sūtra, which translates the four notions of the Diamond Sūtra into modern language, and extends the true meaning of Buddhism where there is infinite merit in giving without notions; supreme compassion in living in the absence of a self; true freedom in living without abiding; and true attainment in practicing without gain. This is the same philosophy as Venerable Master Hsing Yun's saying of adopting a world-transcending spirit in handling worldly affairs. Here, the world-transcending spirit refers to emptiness, and worldly affairs refer to existence. This is Venerable Master Hsing Yun's endeavor in liberating beings through the notion of viewing “nothing as something.” And from this concept began Venerable Master Hsing Yun’s lifelong practice of the Four Insights of Emptiness.
