““According to the Trika system, yoga is that theological practice which helps in attaining the realization of absolute unity between the practitioner and Absolute Reality, that is, between the yogin and God. As it says in the Malinitantra: The unity of one (a finite being) with another (Almighty God) is called yoga by Shiva yogins (Malinivijayatantra, IV.4). Practitioners of yoga are advised to realize their forgotten true nature and to recognize themselves as none other than the Absolute, Paramasiva. This realization is said to be readily attainable through Trika yoga, when aided by both an intense devotion for the Lord and by the correct theoretical knowledge of the pantheistic absolutism of Shaiva monism. Theoretical knowledge removes the yogins’ mental confusion and misconceptions about Reality, and devotion refines their hearts so that they become capable of actually feeling and experiencing the truth of Shaiva monism. The yoga of Abhinavagupta is thus an integral process of developing both the head and the heart. People with no mental clarity cannot understand the truth, while those without heart cannot digest. — B. N. Pandit, Specific Principles of Kashmir Shaivism (3rd ed., 2008), p. 95–96.””
