Pain from the world comes in, always. We build our dams, we fortify them with steel, we argue over new construction methods and stronger plans, and every single one fails. Eventually the pain rushes in with the force of a raging wall of water, there's not supposed to be a dam, it allows so much force to build up.
We need to let the water flow, let the pain happen consistently, construct a different device one inside yourself. It's a very simple device, just a balanced scale. Pain flows in, calculate it, feel it, balance it with love, eject the love.
Pain in,
Love out.
Always.
