Indigo Children, also known as Blue Ray Children, Rainbow Children, and Crystal Children, these are the names that all refer to the same group of souls that have recently incarnating here on Earth. The reason why they are referred to as Indigo or Blue Ray is because that is the color of their aura that states their spiritual rank or level of consciousness which is very high; they are our teachers, light workers and without them this planet will not make it through the next step of our spiritual evolution. I call this phase The Ascension.
