Madhyamaka
Beginning with Nāgārjuna, Madhyamaka discerns two levels of truth, conventional truth (everyday commonsense reality) and ultimate truth (emptiness). Ultimately, Madhyamaka argues that all phenomena are empty of "svabhava" and only exist in dependence on other causes, conditions and concepts. Conventionally, Madhyamaka holds that beings do perceive concrete objects which they are aware of empirically. In Madhyamaka this phenomenal world is the limited truth - "samvrti satya," which literally means “to completely cover, conceal, or obscure” and arises due to ignorance. This seeming reality does not "really" exist as the highest truth realized by wisdom which is "paramartha satya" ("parama" is literally “supreme or ultimate,” and "artha" means “object, purpose, or actuality”)"," and yet it has a kind of conventional reality which has its uses for reaching liberation. This limited truth includes everything, including the Buddha himself, the teachings (Dharma), liberation and even Nāgārjuna's own arguments. This two truth schema which did not deny the importance of convention allowed Nāgārjuna to defend himself against charges of nihilism, understanding both correctly meant seeing the middle way:"Without relying upon convention, the ultimate fruit is not taught. Without understanding the ultimate, nirvana is not attained."
