The brahman Dona saw the Buddha sitting under a tree and was impressed by his peaceful air of alertness and his good looks. He asked the Buddha:

“Are you a god?”
“No, brahman, I am not a god.”

“Then an angel?”
“No, indeed, brahman.”

“A spirit, then?”
“No, I am not a spirit.”

“Then what are you?”
“I am awake.”
-Anguttara Nikaya
