This paper examines the idea of the Mutual-Identity and Mutual-Entering(相卽相入) of Huayen Buddhism through tracing developments of Huayen's metaphor of counting ten coins(數十錢法). Although Huayen buddhists accept the basic idea of Sanlun's Mutual-Identity(相卽) as it is, there is a definite difference in its explanation. The Huayen uses the metaphor of counting ten coins for it. Euisang(義湘) unfolds his idea of the Mutual-Identity and Mutual-Entering upon the basis of two-fold structure of Jungmun(中門, Mutual-Entering) and Jeukmun(卽門, Mutual-Identity). He reconstructs the idea of Sanlun's Mutual-Identity as Huayen's Mutual-Entering, and adds Huayen's own idea of Mutual-Identity as a new view-point.Jungmun means, he says, the concept of the differentiation aiming at the integration. On the contrary, Jeukmun can be explained as the integration pointing at the differentiation. In other words, this explains the side of Buddha's delivering sentient beings; and that does the side of sentient beings' seeking the enlightenme- nt. Euisang's two-fold structure implies that Huayen's idea of Mutual-Identity emphasizes the equality much more than Sanlun's. Fazang(法藏) systematizes Euisang's metaphor of counting ten coins. The most remarkable point in his reformed theory is the idea of the Substance-Differing Area(異體門) and the Substance-Sharing Area(同體門). He includes Euisang's Jungmun and Jeukmun in his own Substance-Differing Area, and creates the new area of Substance-Sharing Area. In his new area, we shall see Fazang's intention to emphasize that Huayen Buddhism is the only teaching for Ekayana not for any other.
