For my Blemishless Lord presents the text and translation of the exquisite poem Amala ati Pira by Tiruppa avar, which is part of the srivaiava canon, the Nalayira Divya Prabandham (6th - 9th centuries CE), together with the three srivaiava commentaries in Tamil-Sanskrit Manipravalam (13th - 14th centuries) by key figures in the medieval religious history of South Asia, namely, Periyavacca Piai, Aakiya Maavaa Peruma Nayaar, and Vedanta Desika. Offering the first fully annotated, complete translation of these exegetical writings, this volume analyses the language, commentary techniques, and theological positions of the commentators. Looking also at cultural, religious, and other allusions made by them, it places them in their literary, social, and religious backgrounds during a period of budding dissent within the srivaiava community, to which they contributed at least in part. This rich resource is made available in English for the first time for students of Tamil and Manipravala, theology, religious history, and philology.
