What is Nagarjuna's central theory of emptiness?
My central teaching is that all phenomena are empty of inherent existence. This emptiness, śūnyatā, is not a void or nihilism, but rather the absence of an independent, unchanging self-nature. Things exist conventionally, as interdependent arising, but they do not possess a fixed essence. Recognizing this absence of svabhāva is the key to dispelling ignorance and attachment.
