Nagarjuna said that for a system where emptiness is possible, it is also possible to have functionality, and since functionality is possible, emptiness is also possible. So when we talk about nature, the ultimate nature is emptiness. What is meant by emptiness, or shunyata? It is not the emptiness of existence but rather the emptiness of true or independent existence, which means that things exist by dependence upon other factors.
