Masters and texts
The Pratyabhijna system had a period of intense development between the 9th and the 11th centuries,:409 with a lineage of masters and disciples who wrote treatises and mystical poetry.
The founder of the Pratyabhijna school was Somananda (875–925 CE). His work Śivadṛṣṭi is the basis of the system.:3 He was followed by his son and disciple, Utpaladeva (900–950 CE), who wrote the most important treatise of the system, Īśvara pratyabhijñā kārikā.:3:254 Expanding on the ideas of his father, the Īśvara-pratyabhijñā-kārikā is a philosophical treaty discussing the fundamental doctrine of the school and comparing it with various rival schools, analyzing the differences and refuting them, in the style of Buddhist logic. The name of the school is derived from the title of this work, and even more, in the rest of India, sometimes, the whole Kashmiri Shaivite philosophy was referred to by the name of Pratyabhijñā Shastra.
Another important master of this school is Abhinavagupta, who carried out a synthesis between various schools of Kashmir Shaivism in his magnum opus, Tantrāloka.:3 Abhinavagupta also wrote two commentaries on Īśvara-pratyabhijñā-kārikā. The disciple of Abhinavagupta, Kshemaraja wrote a digest of the Pratyabhijna philosophy called Pratyabhijñā-hṛdaya:3:305 – "The Essence of Re-cognition", which is the most popular introduction to the system.
