「一行三昧」是印度佛教般若經系，提出的百八三昧之一，但早期般若經典中，只能看到對此三昧的一般性詮釋; 到後期大乘佛教結集出的《文殊般若經》，才提出詳盡的解說，而成一套具體可行的禪修方法. 自梁‧曼陀羅仙在中土譯出《文殊般若經》後，中國佛教祖師，特別是天台宗智顗及禪宗道信，便深受影響，各自將此三昧納入自宗禪修體系，並在不同程度上，對此三昧進行方法的吸納，與內容的詮釋發揮. 從佛教思想史來看，智顗與道信對此禪法的吸收與詮釋，深遠的影響其後門人. 本文即以「一行三昧」禪法為核心，一方面上溯其在般若系經典群中的本義，另一方面則下探智顗與道信，是如何對「一行三昧」作出理解與詮釋. 本文分為六章： 【第一章 導論】 揭示研究動機. 研究方法. 論文組織與內容大意. 【第二章 般若經系的一行三昧】 論述「一行三昧」在般若經系的本義. 比較《文殊般若經》三種譯本，對一行三昧的不同詮釋; 並對曼陀羅仙譯本《文殊般若經》一行三昧，所隱含的二種修行進路提出說明. 【第三章】 先討論《大乘起信論》如來藏思想的佛性理論，並對《起信論》提出的真如三昧. 一行三昧，說明其在本體論及禪修理路上，已融合《楞伽經》與《文殊般若經》二部經典的思想. 【第四章 天台宗的一行三昧】主對《摩訶止觀》的文本架構，及智顗門人對一行三昧的詮釋，說明智顗的一行三昧在禪修的實質上，已導入天台宗「十乘觀法」. 「一念三千」的觀心內容. 【第五章】則說明道信的一行三昧禪法，及論述道信的一行三昧與《楞伽經》如來禪. 達摩禪的內在關係. 【第六章 結論】 依前四章的討論結果，把整篇論文作出總結.
