The last frontier of humanity is not the evolution of technology, but it is the evolution into Higher Consciousness. The projected world outside is the mirror image of the world inside. Every relationship becomes a tool for the evolvement of Higher Consciousness.
To become fully conscious of the true self, we need to understand that every single human being that comes into our space is a true reflection of us. If the person shows beauty, grace and wisdom, they are truly reflecting us, if they show greed, selfishness, or cruelty; they are also truly reflecting us. We live our lives denying our dark side.
