本文從佛教飲食規範角度切入，探索藏外文獻中有關五辛禁忌概念的意涵。不同於過去學者運用藏經文獻資料，指出禁食五辛的緣由環繞在潔淨與情意克制兩大面向。筆者注意到在敦煌遺書的五辛主題寫卷，提供了藏經前所未見的材料與視角，讓我們得以窺見五辛禁忌的不同闡釋與教化運用。本文利用現存敦煌寫卷，嘗試解讀五辛相關文本的內容，並釐清五辛禁忌不只是一種佛教飲食規範下的產物，而是隨著佛教的傳播，轉為一種教法譬喻，用以宣揚宗教修持的關鍵。因此推知，五辛禁忌的意涵發生了轉變，逐漸成為一種特殊的漢傳佛教文化符號。此外，本文嘗試廣蒐與五辛主題或內容與五辛相關的寫本，進行跨文本比對，並梳理出寫本間的互文交織情形。最後從禪修醫方、五辛警示兩個面向來綜合解析這些寫本的互文關係。這些敦煌材料提供了我們有別於藏經文獻的訊息，也豐富了我們對禪修醫方的寫作以及五辛寓意的理解與視野。

This article explores the meaning of the five-spice taboos from the perspective of Buddhist dietary norms in non-canonical literature. Unlike previous scholars who relied on the Chinese Buddhist Canon, it highlights that abstaining from the five spices is driven by concerns of cleanliness and emotional restraint. The Dunhuang manuscripts on this theme provide unprecedented materials and perspectives within the canonical works, shedding light on various interpretations and enlightening applications of these taboos. By utilizing the existing Dunhuang scrolls, the article interprets the related content, clarifying that these taboos extend beyond Buddhist dietary norms and have transformed into a metaphor for religious practice. Consequently, the evolving meaning of the five-spice taboos has gradually become a distinct symbol of Chinese Buddhist significance.
Furthermore, this article attempts to extensively search for manuscripts related to the theme or content of the five-spice taboos, conducting cross-text comparisons and sorting out the intertextual interweaving among manuscripts. Finally, through a comprehensive analysis from the perspectives of medical formula for meditation instructions, and warnings related to the five pungent spices, this study examines the intertextual relationships among these manuscripts. These Dunhuang materials provide us with information that is distinct from the canons, enriching our understanding and broadening our perspectives on medical formula for meditation instructions, and the symbolic meaning of the five-spice taboos.
