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.
