This book serves as an introductory study of Tantric Saivism in its original scriptural sources. It traces the features and content of the canon of the SAaiva Tantras, making use of many unpublished manuscripts from Kashmiri Saiva authors. The book is also an introduction to the literature of the Kubjikamata. As Kundalini, Kubjika is worshipped as the Goddess who is curled up and sleeping, waiting to be awakened. The author explores her place in the Tantric literature.
