In the series of papers of which this is the first, I hope to give, as opportunity allows, as full as account as possible of the contents of the Bhakta-māla of Nābhādāsa, a work of which the importance has long been recognized, but the difficulties of which have hitherto repelled serious students. It is acknowledged as the great authority in regard to the history of the saints of the Bhāgavata reformation started by Rāmānuja, Madhva, and other, in the twelfth century A.D., and also, incidentally, as a compendium of the tenets of that religion. Indeed, a somewhat minute study of the work has convinced me that it is impossible to understand the various phases of modern Hinduism as professed by the Vaiṣṇava sects without a knowledge of its contents.
