Enlightenment is simply being one with light. Light, the visual form of energy, is the essence of everything. Enlightenment is being one with everything. To the enlightened, this realization is  manifested in the many faces of enlightenment.

As E=M*C*C (energy equals mass times the speed of light squared) is M=E/C*C (mass (all that there is) is energy divided (slowed down) dramatically by the speed of light squared), all things are essentially infinite manifestations of light.

As energy is all there is, all things (however seemingly real and independent of energy) are just an illusion disguising energy. As energy is all there is, the Big Bang is all there is. The Big Bang happens at one time. Hence, there is no such thing as time. The appearance of things sequentially is an illusion that creates the illusion of time as well.
