Question: Nagarjuna said that sentient beings are empty of what?

Is For Nagarjuna, it is not merely sentient beings that are empty of atman; 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. a good answer to this question?
yes
