Indian Tantric practice has an unbroken tradition dating back thousands of years. One of its greatest exponents was Abhinavagupta, the 10th century spiritual teacher, scholar, poet and mystic whose masterwork, Tantraloka, is encyclopaedic in length. We present here the Tantrasara, Abhinavagupta s own brief prose guide to Tantraloka, in a masterful English translation by the renowned Pandit H. N. Chakravarty, who completed it shortly before his death. This long-awaited volume takes us directly into the world of esoteric Tantric philosophy and practice. Dealing with topics such as the nature of the ultimate reality, consciousness itself, the creative energy underlying all manifestation, and the ritual and inner practices that awaken, sustain, and bring this awareness to fruition, it lays a solid foundation for understanding Tantric spiritual practice with clarity and depth.
