There were Dharmapāla and Chandrapāla who gave a fragrance to Buddha's teachings, Guṇamati and Sthiramati of excellent reputation among contemporaries, Prabhamitra of clear argument, and Jinamitra of elevated conversation, Jñānachandra of model character and perspicacious intellect, and Śīlabhadra whose perfect excellence was buried in obscurity. All these were men of merit and learning, and authors of several treatises widely known and highly valued by contemporaries.
