Academic study of the tantric traditions has blossomed in recent decades, in no small measure thanks to the magisterial contributions of Alexis G. J. S. Sanderson, until 2015 Spalding Professor of Eastern Religions and Ethics at Oxford University. This collection of essays honours him and touches several fields of Indology that he has helped to shape (or, in the case of the Saiva religions, revolutionised): the history, ritual, and philosophies of tantric Buddhism, Saivism and Vaisnavism; religious art and architecture; and Sanskrit belles lettres. Grateful former students, joined by other experts influenced by his scholarship, here offer papers that make significant contributions to our understanding of the cultural, religious, political, and intellectual histories of premodern South and Southeast Asia.
