It signifies balance, moderation, and patience, as embodied by Delphine and Eurus.

This card is about balance and patience. An angel stands between you and unworthy causes. Is something in your life-threatening to overwhelm and upset the balance? Perhaps you are the type that jumps in to help others solve problems. What sacrifices in life are made for those we care for, and we must not forget to care for ourselves. Make an effort to practice awareness of balance in your breath. 

Affirmation

All is perfect balance.
