T’ien-t’ai Zhiyi (538-597 智顗) in his early monograph Bodhy-samādhi (《覺意三昧》) and late period book Mohe-zhiguan have exposittd the thought of bodhy-samādhi. In his exposition, bodhy-samādhi is not only a synthesis of the meditation method of Mahayana and Hinayana Buddhism, but also the most important meditation in T’ien-t’ai Buddhism. In this article, I exposit the course of the development of bodhy-samādhi in the history of Buddhism, and tackle the topic of the relationship of six “Chi” (Identity) and the six kind of seven Bodhy-samādh. After the exposition of the method of bodhy-samādhi in T’ien-t’ai Zhiyi’s different books, I tackle the theory of bodhy-samādhi from the perspective of “destruction of the attachment to all beings” in Mohe-zhiguan, in order to explain the relationship between bodhy-samādhi and T’ien-t’ai Chi-I’s late teaching about perfect teaching.
