The Center Ground
Fire burns, Water sinks, Wood pushes, and Metal cuts. All four are extreme trajectories. Earth (To) simply sits in the center and absorbs. The Earth element represents trust, patience, borders, and the changing of the seasons. Without Earth, the other elements would destroy each other.
People with a heavy Earth chart are the mediators of their families and friend groups. Everyone comes to them to complain, but the Earth person feels they have nowhere to put their own garbage.
Learning to Erupt
A mountain that absorbs everything eventually becomes a volcano. Earth types must learn to selectively reject people. Complacency is the shadow side of Earth; taking a selfish, definitive stance is their salvation.
