Harmony is universal, suffering individual.
Harmony inevitably erases the pain of assumed conflict and isolation. No matter how long it takes, the intention of harmony prevails. Everything returns to the same benevolent will.
Resisting unity is accepting separation. Accepting separation as anytihng other than temporary play by the Infinite is immediately unpleasant. Willingness to yield to the wisdom of the whole, taking form endlessly, offers a doorway out of the land of illusory pain.
The unity of the whole, touched wiht our consciousness offers us the use of aspects like harmony to dissolve the illusions of isolation and conflict.
