The philosophical texts Spandakārikā and Pratyabhijñāsūtra are core scriptures associated with the Kashmir Śaivism school of thought.
The Spandakārikā explains the concept of 'Spanda' (vibration or cosmic pulse), a fundamental principle in this tradition.
The Pratyabhijñāsūtra delves into the 'Pratyabhijñā' (recognition) doctrine, aiming at the realization of the self's identity with the ultimate reality, Śiva.
Both texts represent significant contributions to the philosophical landscape of Śaivism, specifically its Trika or non-dualistic aspect.
