Kashmir Shaivism tradition is a 20th-century umbrella-term for a body of Sanskrit exegetical literature from several non-dualist Shaiva-Shakta tantric and monistic religious traditions, often used synonymously for the Trika-school or the "Philosophy of Recognition" (Pratyabhijñā). These traditions originated in Kashmir after 850 CE, as an adaptation to upper-class Hindu norms of 'wild' tantric Kaula traditions. Trika Shaivism later spread beyond Kashmir, particularly flourishing in the states of Odisha and Maharashtra.
Defining features of the Trika tradition are its idealistic and monistic pratyabhijna ("direct knowledge of one's self," "recognition") philosophical system, propounded by Utpaladeva (c. 925–975 CE) and Abhinavagupta (c. 975–1025 CE), and the use of several triades in its philosophy, including the three goddesses Parā, Parāparā, and Aparā.
