According to the Shaiva Siddhanta tradition, which is a major school of Shaivism, Parashiva is absolute reality which is beyond human comprehension and is beyond all attributes.
[8] Kashmiri Shaivism describes how all of reality, with all of its diversity and fluctuation, is the play of the single principle, Paramashiva.
The ontological nature of Paramashiva is beyond human knowledge and articulation, yet it can be experienced directly through mystical intuition.
It later spread beyond Kashmir, with its great scholar Abhinavagupta calling it "Trika" (meaning "the Trinity").
[12][13] Defining features of the Trika tradition are its idealistic and monistic Pratyabhijna ("Recognition") philosophical system, propounded by Utpaladeva (c. 925–975 CE) and Abhinavagupta (c. 975–1025 CE), and the centrality of the three goddesses Parā, Parāparā, and Aparā.
