The Lion’s Roar that Proclaims Zhantong (Also spelled Shentong) focusses on the issues of emptiness and the two truths as they are proclaimed within the Zhantong system. The text begins with a clear explana- tion of the lineage of teachers through which the Zhantong view came down from the Buddha, then mentions the main texts of the system, and then lays out the particulars of the view of zhantong emptiness and the two truths corresponding to that view of emptiness. All of this happens in very short but cogent piece at the beginning of the text. Following that, most of the text consists of a long argument with opponents of Zhantong. The argument goes through a number of major points of disagreement between Zhantong followers and their opponents in order to expose the particularly subtle and hard to understand view of Zhantong. Both sides are very well versed in the Buddha’s teaching with the result that the arguments engage deep points of philosophy which cannot be understood without significant knowledge of the system.
