You're here as a spiritual being having a temporary human experience. You come to know your essence - that you came from an energy, a vibrational frequency. Everything in the universe is frequencies. Even things that look solid are all frequencies, all movement. Einstein said nothing happens until something moves. This chair I'm sitting in is moving. It may be hard to imagine, but if you took a microscope and really got in there, you'd see the spaces and a lot of particles all in movement.
