The consciousness and the being are two separate entities. When the consciousness falls in love with its being, then the two will both find true satisfaction, contentment, and happiness. That is the only way to true peace.
The person in the mirror is a whole new person. They embody who you are in reality. All the failures, the sadness - they are only your body wrestling with the will of is consciousness. If your consciousness can look into the mirror and understand that the image is its one true equal, the only person who can truly understand every part of their being and make them happy, then can the entity find true satisfaction and contentment.
TL;DR - You are your own best friend.
