Using the four elements to create the fifth. Attaining perfection with all five elements of life (assuming such a thing as "perfection" exists) requires a complete balance of all four elements (Fire, Water, Air, and Earth), the mastery of skills belonging to each of them, and a personality free from negative traits belonging to any. By creating this sort of equilibrium, we can effectively establish an alchemical process within our own souls, transmuting four different forces into a whole new element - Aether.
