The Rider-Waite-Smith card focuses on a more prosaic subject than the Thoth Tarot Card. Hence, the more mundane meaning illustrates the great difficulty of obtaining reward. Waite's card presents the boatman laboriously poling souls across the River of Spirit. The Swords on board just add more to his burden. For in truth, with greater mind, comes greater responsibility.
The Angels of the Decan are: Rehaayal and Yeyezeil . The Six of Swords is influenced by Tiphareth in the Astral World [ Yetzirah].
The air sign of Aquarius, is ruled by Saturn, which tends to stabilize the fleeting qualities of Mercury. The positioning of Mercury in Aquarius, a Mind sign, leads naturally to science and humanitarianism so success is the result of Saturn's work in this aspect. Now the cutting power of Swords is turned toward the positive, and the Rose is resurrected after being war torn in the Five of Swords severity of Geburah.
In the Thoth 6 of Swords, the swords all come together at a point in the restored Rose- Cross of 6 squares, which Crowley calls, "The Rose-Cross at the central secret of Scientific Truth." The Scientific Truth being, you are a "self-reflection" of your Soul-psyche collective and that all that you see, experience etc, is "imagined". We are all Mind, the body is just how the invisible Mind can measure it's thoughts, for self-awareness requires measurement. Hence, the 6 of Swords, is the coming together of the Spirit-Mind-Body paradigm.
The human body is represented as the cross. Hence, with the 6 of Swords, we have the definitive meaning of "success after anxiety and trouble", for the Way of the Cross is suffering before ascension. Here,Tiphareth shows the perfect balance and idea of the card, as all moral and mental faculties are perfectly balanced, won by great effort, but hard to hold in a ever-changing world of political propaganda and commercialized morality which form a white noise in the brain. This prevents the brain from receiving the real transmission frequency form the Soul/Psyche to the avatar body. The Thoth Tarot 6 of Swords represents the "Holy Hexagram", a symbol of perfect psychosomatic communion and health.
The negative of this card, would be confusion because of extreme mental activity producing conflicting thoughts, ambiguity and indecision. As always, the positive or negative of a card depends on the accompanying cards.
