One of Wicca's best known liturgical texts is "The Charge of the Goddess". The most commonly used version used by Wiccans today is the rescension of Doreen Valiente, who developed it from Gardner's version. Gardner's wording of the original "Charge" added extracts from Aleister Crowley's work, including "The Book of the Law", (especially from Ch 1, spoken by Nuit, the Star Goddess) thus linking modern Wicca irrevocably to the principles of Thelema. Valiente rewrote Gardner's version in verse, keeping the material derived from "Aradia", but removing the material from Crowley.
