Ebook: Spandapradipika : A Commentary on the Spandakarika by Bhagavadutpalacarya

This commentary is by Bhagavadutpala, also known as Utpala Vaisnava, who lived in 10th century Kashmir. It is important both because it is early and especially because it contains copious references to Pancaratra sources - the earliest dateable ones so far recovered.
