When your heart is tired, when you are deeply lost, it gently stays by your side and delivers a gentle light of healing. A stone that quietly releases anxiety and fear, and returns you to your true self. It gives you a sense of security that you are protected, and the courage to take a step forward at the same time, illuminating the path towards happiness. "It's okay. You are not alone." The angel's wings gently convey that message to you.
