(Thirty-four) The śramaṇa Dhyāna Master Huiwen walked alone between the Yellow and Huai rivers during the reign of Qi Gaozu. His Dharma gate was not understood by worldly people; living beneath heaven and upon the earth, none knew its heights and depths. Reading the Madhyamaka-śāstra, he attained awakening; as the treatise was spoken by Nāgārjuna, he received instruction from afar. He is the Second Patriarch of the Tiantai school, the Venerable of Northern Qi. (Account of the Nine Patriarchs.)
