The Rays are expressions of the Aspects of Source God and are the builders, of all that exists. They are responsible for the evolution of consciousness, as it exists in minerals, plants, animals, humans. Each particle of matter is destined to evolve through self-consciousness, then through soul-consciousness and then God-consciousness. Since humans have the capacity to be self-conscious we also contain the ability to ultimately attain Cosmic Consciousness or God-consciousness.
The Rays teach us the major qualities of the Universal Christ, qualities we on the Ascension path must embrace.
