Abstract
This paper has attempted to present Wonch'uk's Ban-ya pa-ra-mil-da sim gyeong chan (般若波羅蜜多心經贊) or Commentary on the Heart Sūtra which was written in classical Chinese in the 7th century. As an example of the intellectual analysis of a sūtra, Wonch'uk's Commentary is an important text that has exerted asignificant influence on East Asian Buddhist thought. A prominent Korean Yogācāra scholar, Wonch'uk authored twenty-three works during his lifetime; unfortunately, all but three have been lost. The Commentary on the Heart Sūtra is the shortest among his extant writings, yet it clearly reflects his incomparable erudition. To date, there has been very limited research on Wonch'uk and his thought in both the East and West. Utilizing Wonch'uk's original Chinese text,this paper will examine the distinctive features of Wonch'uk's Commentary which may offer the contemporary readers an opportunity to remind the importance of sūtra study and the engagement in sūtra exegesis.
