Now does my project gather to a head:
My charms crack not; my spirits obey; and time
Goes upright with his carriage. How’s the day?

– William Shakespeare

The Tempest, Act 5, Scene 1. Dressed in his magic robes and accompanied by Ariel, the powerful Prospero says that his plan of dealing with his enemies is reaching its conclusion, his magic charms are not breaking, his spirits obey him and everything is running to schedule.
