"Everything and nothing"

The poet is a forger who forges so completely that he forges even the
feeling he truly feels as pain. —Fernando Pessoa

A fellow astrologer, Pessoa wrote initially to correct errors he spotted in Crowley’s calculations. Crowley responded, warmly, in letters to Pessoa that he signed “666.”
