Tiantai Zhiyi established his own unique interpretation, which made the Lotus Sutra supreme as “the teaching that unifies all that is good” and “the comprehensive unifying teaching.” In this we can see his intention to use the Lotus Sutra to create a unifying Buddhist summa and to bring the disputes over interpretation to an end. He composed the work during the unification of the nation under the Sui dynasty (589-618). The establishment of a unified Buddhism indicated that there existed a comprehensive and unifying Buddhist view of truth, the world, and human life. Thus was born Tiantai Zhiyi’s system of thought, comprehensive and great in both form and content.
