佛祖統紀 6.18

6.18

贊曰。南岳以所承北齊一心三觀之道傳之天台。其為功業盛大無以尚矣。故章安有曰。思禪師。名高嵩嶺。行深伊洛（喻名行之高深）十年常誦。七載方等。九旬常坐。一時圓證（見天台別傳）師之自行。亦既勤矣。至於悟法華三昧開拓義門。則又北齊之所未知。故荊溪亦云。文禪師但列內觀視聽而已（見止觀大意）可不信哉。

The eulogy says: Nanyue transmitted the path of the threefold contemplation in a single mind, which he had received from Beiqi, to Tiantai. The greatness of his achievements was unsurpassed. Thus Zhāng'ān said: 'Dhyāna Master Si's fame was loftier than Mount Song, and his practice was deeper than the Yi and Luo rivers (an analogy for the height and depth of his renown and practice). For ten years he constantly recited; for seven years he practiced the Vaipulya [penance]; for ninety days he constantly sat; and in a single moment he attained perfect realization (see the Separate Biography of Tiantai).' The Master's own practice was indeed diligent. As for his awakening to the Lotus Samādhi and his opening of the doctrinal portals, these were things that Beiqi had not yet known. Therefore, Jīngxī also said: 'Dhyāna Master Wen only set forth internal contemplation of seeing and hearing, nothing more (see the Outline of the Great Calming and Contemplation).' How could this not be trusted?
