《壇經》最大醒世意義在找回自己、見到自性。但是仍有諸多有關自性的問題有待研究。為免以訛傳訛，筆者依據印度梵本漢譯的《文殊師利所說摩訶般若波羅蜜經》及相關典籍深入探索、比較、闡明、證實《壇經》的見地、修行和果位。本文將不同版本的《壇經》，以文獻學的方式，進行鑑別、分類、比較和編目，並輔以田野調查的研究方法，來研究《壇經》中的「自性」。接著從《文殊般若》的一行三昧到《壇經》的自性，呈現出修行的道和果，以及不二的中道思想。本文第一章是緒論，第二章《壇經》各種版本的文獻處理，第三章《壇經》「自性」相關論題，第四章是從《文殊般若》解析《壇經》自性的開顯，第五章是結論，由此依次彰顯人人本具之「自性」。
The greatest awakening meaning of the Platform-Sūtra is to find oneself, and to see the Self-Nature. However, there are many problems related to the Self-Nature to be studied. To keep from confusion, I present the Mahā- Prajñāpāramitā Sūtra (translated from Sanskrit) and related scriptures to explore, compare, clarify, and prove the viewpoints, path and results of the Platform-Sūtra. Applying bibliography, different versions of the Platform-Sūtra are identified, classified, compared ,cataloged, and supplemented by field research methods, to study the self-nature of the Platform-Sūtra.Then, from the samadhi in one practice of Mañjuśri’prajñā to the Self-Nature of the Platform-Sūtra, the practice of the path and fruit, as well as the middle-way thought of non-duality are presented. Step by step, the first chapter is Introduction. Chapter two focuses on the document processing of the various versions of the Platform-Sūtra. Chapter three deals with the Platform-Sūtra’s related issues concerning Self-Nature. Chapter four explains the development of Self-Nature of the Platform-Sūtra with Mañjuśri’prajñā. Chapter five is the conclusion. We evolve from all directions to manifest the Self-Nature that everyone possessed.
