“Social reality” is a reference to the idea that everything that humans say to each other is mediated by political or social concerns, such that truth is being constantly warped as it passes through people’s brains, without the people involved even being aware of it. The term “social reality” specifically refers to the “alternate reality” that is created by these truth-warping distortions.
“Mana” means “ability to see the world as it genuinely is, without being affected by social reality.” When you have a lot of this ability, you gain the miraculous power to affect other people’s perception of reality, because they are still existing in a reality-distortion field even if you aren’t—so their social conceptions will move out of the way to make room for yours.
