The horses are a reference to the Bhagavad Gita (Hindu scriptures). There are five horses which symbolize the five senses. The singer is flying over the horses, that is she is rising above the simply material and entering the spiritual world. She argues against the premise that "all things pass into the night" which is symbolic of a type of nihilism and the materialism of the secular world.
