but I need a sutra source to use it.

When the Buddha wandered around India shortly after his enlightenment, he encountered several men who recognized him to be a very extraordinary being.

They asked him, "Are you a god?"

"No," he replied.

"Are you a reincarnation of god?"

"No," he replied.

"Are you a wizard, then?"

"No."

"Well, are you a man?"

"No."

"So what are you?" they asked, being very perplexed.

"I am awake."
