"He couldn't walk — I convinced him that he could," says the Ancient One. "What if I told you that your own body could be convinced to put itself back together in all sorts of ways?"
"You're talking about cellular regeneration!" said Strange. "That's bleeding-edge medical tech!"
As the Ancient One's spiritually driven perspective becomes clear to him, however, Strange brashly dismisses it. "I do not believe in fairy tales about chakras or energy or the power of belief," he says. "There is no such thing as spirit! We are made of matter and nothing more."
Then the Ancient One punches Strange's astral form out of his physical form, which, naturally, comes as something of a shock to him.
"Why are you doing this to me?" he manages to say once he's returned to his body.
"To show you just how much you don't know."
And then things get really trippy after the Ancient One touches Strange's forehead and sends him into an explosive kaleidoscope of psychedelic imagery that seems destined to make Doctor Strange a new stoner classic.
