It is the formalized theology of the divine revelations contained in the twenty-eight Saiva Agamas.

God is Satchitananda and Parasiva, existing simultaneously.
Siddhantam holds that all the elements of Creation becomes united with God and back to pre-creation stage. Siddhanta is the philosophy of choice of Saivite mystics and yogis.
