Ace of Swords
According to the Tarot of Ceremonial Magick by Duquette, the general divinatory meaning is "Primordial intelligence. Seed of the mind. Invoked force for good or ill." Willis nots that in the Magickal Tarot this Trump is illustrated with the heads of a male figure and a female figure, emblematic of the Air sign Gemini. His explanation is that Esoteric greek learning represented this sign a sa pair of male twins. The ninth House of a person's horoscope is the key to their inner nature. In esoteric astrology, the Ninth House is connected iwth one's past Karma. The Ninth House is also used to judge what type of teacher a particular student will respond most readily to as well as indicating the Magickal Path to which he or she would be best suited. (Magick and the Tarot, Tony Willis, Aquarian Press, 1988).
Crowley in his Book of Toth states that the Ace of Swords is hte primordial Energy of Air, the Essence of the Vau of Tetragrammaton, the integration of the Ruach. He attributes this card as the "first card directly to be apprehended by the normal consciousness of Mankind. Crowley seems to recognize the twin aspect in his observation: "In nature, the obvious symbol of Air is the Wind, "which bloweth withersoever it listeth". It lacks the concentrated Will of Fire, to unite with Water: it has no corresponding passion for its Twin element, Earth." (Book of Thoth, page 202).
