The importance of Kashmir Saivism lies in the fact that an independent school of Saivism, with its own specific ethos and orientation, emerged from the soil of Kashmir during the eighth century of our era, which till the end of the twelfth century made great strides both philosophically and theologically. The type of Saivism that emerged during the eighth century is deeply rooted in the religious outlook which has served as the substratum for the flowering of various schools of Saivism, and which ultimately terminated in the rise of such philosophical schools as the Spanda and the Pratyabhijna.
The author of the book has made every attempt at explaining as comprehensively as possible the complex theoretical thinking of the Trika. The Trika, although non-dualistic in orientation, does not obliterate the existence of the person, and that is why it accepts Reality as being of the nature of I-consciousness. According to Trika, Reality is both prakasa and vimarsa, and so the world we live in is an actual manifest condition of the Absolute. Also its theology of divine kenosis discloses that God is not far away from us, but as light of consciousness constitutes our essential nature. [via]
