This is the first full study, translation, and critical annotation of the Essence of True Eloquence, by Tsong Khapa (1357-1419), universally acknowledged as the greatest Tibetan philosopher. The work is a study of the major schools of Mahayana Buddhism, known as Vijnanavada and Madhyamika, and an explanation of the Prasarigika (Dialecticist") interpretation of Madhyamika ("Centrism"). Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
