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.
