In his Introduction and in his exposition ofthe cour commentaries, the auhtor shows both how the Spanda tradition contributes to the other schools of Kashmir Shaivism and how it is different from them. He presents for the first time a detailed treatment of this tradition and an analysis of its dvelopment. The aim is to offer a method that affords access by the general reader to the wonderful world of the Spanda Yogi through which she travels to the liberating realization of her authentic identity vibrant with the vitality of the universal pulse of Shiva.
