Rajanaka Ká¹£emarÃÂja (à ¤Âà ¥Âà ¤·à ¥Âà ¤®à ¤°à ¤¾à ¤Â) (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 Ká¹£emarÃÂja's life or parentage. His chief disciple was a sage known as YogÃÂraja.
Ká¹£emarÃÂja's magnum opus was the PratyabhijñÃÂhá¹Âdayam ('The Heart of Self-Recognition'). In this text, Ká¹£emarÃÂja explains the main tenets of the Pratyabhijñàphilosophy 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.
The text elucidates the main tenets of the pratyabhijñàsystem in a succinct set of sutras, expounding the core of the philosophy and explaining how self-recognition arises within, culminating in the consciousness of Shivoham (I am Shiva). PratyabhijñÃÂhá¹Âdayam consists of 20 aphorisms plus a commentary by Ká¹£emarÃÂja himself. Translations are given by:
