Utpaladeva

Utpaladeva (c. 900–950 CE) was a Kashmiri philosopher and theologian from Kashmir. He belonged to the Trika Shaiva tradition and is a thinker of the Pratyabhijñā school of monistic idealism. His ''Īśvarapratyabhijñā-Kārikā'' (IPK, ''Verses on the Recognition of the Lord'') were the important and central work of the Pratyabhijñā school. Utpaladeva was a major influence on the exegete Abhinavagupta, whose works later overshadowed those of Utpaladeva. However, according to the Indologist Raffaele Torella "most of Abhinavagupta’s ideas are just the development of what Utpaladeva had already expounded." Provided by Wikipedia
