Yogācāra and Madhyamaka philosophers demonstrated two opposing tendencies throughout the history of Buddhist philosophy in India, one which worked to separate and distance the two systems and one tendency which worked towards harmonizing them. The harmonizing tendency can be seen in the work of philosophers like Jñānagarbha (8th century), his student Śāntarakṣita (8th century) and also in the work of the Yogācāra thinker Ratnakaraksanti (c. 1000). These thinkers also saw the Yogācāra "Alikākāravāda" ("false aspectarian", those Yogācāras who believe that mental appearances are false or don't ultimately exist) view as the highest. Śāntarakṣita (8th century), whose view was later called "Yogācāra-Svatantrika-Madhyamaka" by the Tibetan tradition, saw the Mādhyamika position as ultimately true and at the same time saw the Yogācāra view as a useful way to relate to conventionalities and progress students more skillfully toward the ultimate. This synthesized view between the two positions, and also incorporated the views of valid cognition ("pramana") from Dignāga and Dharmakīrti.
