Pratyabhijñā or Pratyabhigyā (Sanskrit: प्रत्यभिज्ञा, romanized: pratyabhijñā, lit. 're-cognition') is an idealistic, monistic, and theistic school of philosophy in Kashmir Shaivism which originated in the ninth century CE. The term Trika was used by Abhinavagupta to represent the whole of Kashmir Shaivism, or to designate the Pratyabhijñā system.
