The ability to use our bodies to control our minds, unique to fleshly creatures, has some potential and, pushed to the limit, might be able to turn this plane from a weird purgatory to the capital of the verse.
Perfect mental stability and maximum intelligence for everyone, relaxing in a hyperrealistic pleasant dream with friends while your subconscious mind and body perform mundane tasks, mastering psychic powers without decades of meditation...
But, watching the state of the world, I don't think this ability would be used for maximizing happiness, freedom, and knowledge. For, as a weird purgatory, this plane is doomed to always receive a corresponding contingent of beings. Some of which will always instinctively strive to live like an animal and enforce the law of the jungle on humanity, or to recreate Hell on Earth.
