Power of the World

The Power of the World (世界の力(せかいのちから)) is a mysterious energy source that comes from the earth, a pulse that forms all the forces and flows in the world like blood vessels extending out everywhere.

Principles
The power of the world is similar to the concept of mana and telesma. Like mana, which is formed from the life force of human beings, the power of the world requires refinement in order to be used. Normally, not too powerful, using a temple or shrine, a large amount of power can be generated.

It is nigh-undetectable power even to normal magicians and is described as being like air. Although, specially trained magicians and feng shui masters can detect and see the force. Apparently, Touma's Imagine Breaker can destroy the power of the world, but is apparently ineffective as if the power simply returns back to the earth it is later destroyed naturally, reverting the power back to the world.

It is referred to by Index after journeying into the Misawa Cram School after following Stiyl Magnus' mana trail. Here, it is referenced as a way to describe the incredibly unnatural way the Misawa Cram School has been set up by Aureolus Izzard, seemingly making the building seem to cut and interrupt the flow of the power of the world under the building.
