Utpaladeva

Utpaladeva (c. 900–950 CE) was a Shaiva tantrik philosopher, theologian and poet from Kashmir. He belonged to the Trika Shaiva tradition and is a thinker of the Pratyabhijñā school of monistic idealism. His ''Īśvarapratyabhijñākārikā'' (IPK, ''Verses on the Recognition of the Lord'') is a central text for the Pratyabhijñā school of Shaiva Hindu philosophy. Utpaladeva was also a tantrik guru and a religious bhakti poet, having authored the influential ''Śivastotrāvalī (A Garland of Hymns to Śiva)'', a collection of Shaiva hymns that remain popular with Kashmiri Shaivas.

Utpaladeva was a student of Somānanda (875–925 CE) and an 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
