In the original poem, the verse says "Without going out of "my" door, "I" can know the ways of heaven." And so to prevent any misinterpretations – and also to make the song a bit longer – I did repeat that as a second verse but made it: "Without going out of your door / You can know all things on earth / Without looking out of your window / You can know the ways of heaven" – so that it included everybody.
