The teachings of Madhyamaka have been the basis of Tibetan Buddhist thought and practice since the eighth century. After the twelfth century, Tibetan scholars distinguished two branches of Madhyamaka: Autonomist and Consequentialist. What distinctions in Madhyamaka thought and practice did twelfth century Tibetan scholars make to differentiate these two branches? This article focuses upon a newly identified twelfth century Tibetan manuscript on Madhyamaka from the Collected Works of the Kadampas: Khu lo tsā ba’s Treatise. Khu lo tsā ba, also known (...) as Khu ston Mdo sde ’bar, was a contemporary of Jayānanda and Pa tshab Lo tsā ba Nyi ma grags and instrumental for the revitalized reception of Madhyamaka in twelfth century Tibet. Khu lo tsā ba’s Treatise outlines a multifaceted understanding of Madhyamaka as the work solely focuses upon the distinctions between Autonomist and Consequentialist Mādhyamikas. The paper outlines the structure and content of the Treatise and identifies six topics that the author emphasizes to distinguish Autonomist and Consequentialist branches of Madhyamaka. Based on an overview of these topics, the paper concludes that the Autonomist/Consequentialist distinction of Madhyamaka was already well developed in twelfth century Tibet and involved a differential of systems that encompassed much more than distinct styles of logical proof.
