 Unlike Jñānagarbha and Bhāvavevika’s realistic Sautrāntika Svātantrika Madhyamaka which presents conventional truth in agreement with the epistemological realism of the Sautrāntika and ultimate truth in agreement with non-foundationalist ontology of the Madhyamaka, Śāntarakṣita and Kamalaśīla advocate the Yogācāra Svātantrika Madhyamaka. They each maintain a basic presentation of conventional truth in agreement with the epistemological idealism of Yogācāra and the presentation of ultimate truth in agreement with the ontological non-foundationalism of the Madhyamaka. Therefore Śāntarakṣita concludes: “By relying on the Mind Only (cittamatra / sems tsam) one understands that external phenomena do not exist. And by relying on this [i.e., Madhyamaka] one understands that even [the mind] is thoroughly nonself.” ([MAK] 23 Dbu ma sa 56a) “Therefore, one attains a Mahāyāna [path] when one is able to ride the chariots of the two systems by holding to the reigns of logic.” ([MAK] 24 Dbu ma sa 56a) By “the two systems” Śāntarakṣita meant, Yogācāra’s account of the conventional truth with Madhyamaka’s account of the ultimate  truth.[13]
