The Law of Equivalent Exchange “Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost. That is alchemy's first law of equivalent exchange.” - Fullmetal Alchemist “The way of water has no beginning and no end. Our hearts beat in the womb of the world. Water connects all things, life to death, darkness to light. The sea gives and the sea takes.” - Avatar The Way Of Water
