The theory of Identity between the Five Secrets and the Five Sacreds ‘Gohimitsu gosho to dotaisetsu 五秘密与五聖同体説’ was described in the Kegon bukko zanmaikan hihozo 華厳仏光三昧観秘宝蔵 volume two written by Myoebo Koben 明恵房高弁 (1173-1232)in his later life. According to that theory, the five saints, ‘Gosho 五聖,’ Mañjusri, Samantabhadra, Maitreya, Avalokitesvara and Vairocana, originating in the Avatamsaka sutra, and the five secret worthies, ‘Gohimitsuson 五秘密尊,’ of Esoteric Buddhism are essentially identical. When Myoe of the ‘Gohimitsu’ is studied, it turns out that Myoe had a keen interest in ‘Gohimitsuho 五秘密法’ from an early stage. He set up in the Hihozo the Gosho theory that he developed from the ‘Sansheng yuanrong’ theory 三聖円融説 of Li Tongxuan 李通玄 (635-730). And he insisted that ‘Gosho’ is the same as ‘Gohimitsu’ in the point that both take great wisdom and great compassion as their essence. However, ‘Gosho’ and ‘Gohimitsu’ are not equal in their mutual relationship but ‘Gosho’ of Huayan is included in ‘Gohimitsu,’ not vice versa. In this paper, the place of Esoteric Buddhist doctrine in Myoe's thought is considered by examining the ‘Dotaisetsu’ described in the Hihozo.
