 Kamalaśīla’s definition of conventional truth makes explicitly clear the synthesis between Madhayamaka and Yogācāra. The Yogācāra Svātantrika Madhyamaka claims that the Yogācāra is right about the presentation of the conventional truth as mere mental impressions, and that this can be seen from the way in which Śāntaraṣita and Kamalaśīla defend this synthesis textually and rationally through relying heavily on the sūtras—Saṃdhinirmocannasūtra, Laṅkāvatārasūtra, Saddharmapuṇḍarīkasūtra and so forth—traditionally supporting Yogācāra idealism. The claim is made here, and Śāntarakṣita does this explicity, that the Madhyamaka and the idealistic doctrines taught in these scriptures are all “consistent.” ([MAV] 91 Dbu ma sa 79a) The works of these two philosophers produce abundant citations from these sūtra literatures stressing the significance of the passages like this from the Laṅkāvatārasūtra: “Material forms do not exist, one’s mind appears to be external.”
