I want to know the answer to the following question:
Nagarjuna said that sentient beings are empty of what?
All the background I'm provided with is that "For Nagarjuna, it is not merely sentient beings that are empty of ātman; all phenomena (dharmas) are without any svabhava (literally "own-nature" or "self-nature"), and thus without any underlying essence; they are "empty" of being independent; thus the heterodox theories of svabhava circulating at the time were refuted on the basis of the doctrines of early Buddhism.". Is that enough to answer the question?
Answer: yes
