Kshemaraja

Rajanaka Kṣemarāja (क्षेमराज) (late 10th to early 11th century) was a philosopher disciple of Abhinavagupta, who was considered a master of tantra, yoga, poetics, and dramaturgy. Not much is known of Kṣemarāja's life or parentage. His chief disciple was a sage known as Yogāraja.

Kṣemarāja's magnum opus was the Pratyabhijñāhṛdayam ('The Heart of Self-Recognition'). In this text, Kṣemarāja explains the main tenets of the Pratyabhijñā philosophy in a succinct set of sutras for students. The work occupies the same place in Kashmir Shaivite or Trika literature as Sadananda's Vedantasara does in Advaita Vedanta.
