Kaecilius : What have you done?
Dr. Stephen Strange : I made a bargain.
Kaecilius : What is this?
Dr. Stephen Strange : Well, it's everything you've ever wanted. Eternal life as part of the One. You're not gonna like it.
Dr. Stephen Strange : Yeah, you know, you really should have stolen the whole book because the warnings... The warnings come after the spells.
The Ancient One : You cannot beat a river into submission; you have to surrender to its current, and use its power as your own.
Dr. Stephen Strange : I control it by surrendering control? That doesn't make any sense.
The Ancient One : Not everything does. Not everything has to. Your intellect has taken you far in life, but it will take you no further. Surrender, Stephen.
