佛祖統紀 22.4

22.4

Those who practiced the way of Tiantai yet were unheard of in later generations were indeed numerous. Is it not because their traces were obscure, their stations lowly, their persons perished, and their lines extinguished? As for those who, although having older records, lack an identifiable teacher, or are mentioned incidentally in other biographies without means of verification: whoever provided even a single incidental benefit to support the Dharma-gate—how could one not take pleasure in recording them? Thus I have composed the Biographies of Those Whose Lineage Succession is Unclear.
