No universe is more vast than the imagination. Everything passes through it first: all arts, philosophies, and inventions, to name a few, and every modification and sidetrack as well. Imagination is the best friend of the conscious mind, the dream tinkerer, and the life's happy companion. Throughout history, we have often stopped external activities (or made them repetitious) in order to enter the infinite regions of the mind, from casual daydreams to disciplined meditations.
