"The Universe is Change; every Change is the effect of an Act of Love;
all Acts of Love contain Pure Joy."

These words are at the "Book of Thoth" a legendary book containing powerful spells and knowledge,
said to have been buried with the Prince Neferkaptah in the City of the Dead
at Menfis, Ancient Egypt. (actual Sakkara, near Cairo)

I don't know if the book really existed, but I liked the phrase to accompany this image..
