Several versions of the Charge exist, though they all have the same basic premise, that of a set of instructions given by the Great Goddess to her worshippers. The earliest version is that compiled by Gerald Gardner. This version, titled "Leviter Veslis" or "Lift Up the Veil", includes material paraphrased from works by Aleister Crowley, primarily from Liber AL (The Book of the Law, particularly from Ch 1, spoken by Nuit, the Star Goddess), and from Liber LXV (The Book of the Heart Girt with a Serpent) and from Crowley's essay "The Law of Liberty", thus linking modern Wicca to the cosmology and revelations of Thelema. It has been shown that Gerald Gardner's book collection included a copy of Crowley's "The Blue Equinox" (1919) which includes all of the Crowley quotations transferred by Gardner to the Charge of the Goddess.
