This book examines the beginnings of the non-dual tantric philosophy of the famed Pratyabhij"a or ''Recognition'' School of tenth-century Kashmir. It includes a critical edition and annotated translation of chapters 1-3 of Somananda's Sivadrsti, the first Pratyabhij"a text ever composed, along with the corresponding passages of Utpaladeva's commentary, the Sivadrstivatti.
