"As it is above, so it is below; as it is below, so it is above". I don't know where that quote comes from, but it is applied to The Magician card in the tarot, and it was in my mind while I made this.
I think the words are essentially about balance. To me, they also carry something in them about grace, which I think is what the card is showing me. Above, below, there is really no separation unless we put it there, and the light of grace is ever present.
