Tsongkhapa defended Prasangika Madhyamaka as the highest view and critiqued the Svatantrika. Tsongkhapa argued that, because the Svatantrika conventionally establish things by their own characteristics, they fail to completely understand the emptiness of phenomena and hence do not achieve the same realization. Drawing on Chandrakirti, Tsongkhapa rejected the Yogacara teachings, even as a provisional stepping point to the Madhyamaka view. Tsongkhapa was also critical of the Shengtong view of Dolpopa, which he saw as dangerously absolutist and hence outside the middle way. Tsongkhapa identified two major flaws in interpretations of Madhyamika, under-negation (of svabhava or own essence), which could lead to Absolutism, and over-negation, which could lead to Nihilism. Tsongkhapa's solution to this dilemma was the promotion of the use of inferential reasoning only within the conventional realm of the two truths framework, allowing for the use of reason for ethics, conventional monastic rules and promoting a conventional epistemic realism, while holding that, from the view of ultimate truth ("paramarthika satya"), all things (including Buddha nature and Nirvana) are empty of inherent existence (svabhava), and that true liberation is this realization of emptiness.
