I want to know the answer to the following question:
A person can awaken from the "sleep of ignorance" by acknowledging the true nature of what?
All the background I'm provided with is that "In Theravada doctrine, a person may awaken from the "sleep of ignorance" by directly realizing the true nature of reality; such people are called arahants and occasionally buddhas.". Is that enough to answer the question?
Answer: yes
