.As a planet, Tiphareth represents the Sun, as a theosophical concept, Tiphareth is the Son who represents consciousness in its most balance and harmonized form. The Son is an interpretation of the Father in mind and form rather than just idea. The Sixes actually represent their respective element at its practical best.
The Six of Wands-Victory, is the conclusion of the outburst of violent energy generated by the Five-Strife. and the battle is won. However, there is a certain instability displayed here, because of the violent outburst of energy applied----causing the "pendulum" of motion to swing high, and soon it will drop into fast downfall. Leading to the 7 of Wands-Valour, where energy is at its last gasp.
The Six of Cups is called Pleasure; the kind of Pleasure that is completely harmonized in body,mind and soul. The Zodiacal sign governing this card is Scorpio--a very deep Water sign of subtle complexities, extreme psychic abilities, and a sensual lover. So, in this union, Pleasure has its most fertile soil and pre-eminately the best card in the Pack. The fact that the Pleasure of Christ-Son, is the perfect balance and harmony of All the Chakras from Crown to Root, and is known as "the orgasm that never stops", will escort the willing Student to deeper and deeper studies into the Tantric Mysteries, which is as the Qaballah, another part of the Gnosis.
The Thoth Deck Six of Swords is called Science, and is ruled by Mercury. This is where the mental element of success has turned away from division and quarrel and there by leaving intelligence to win the goal. Impeccability of mental function.
The Six of Disks is called, Success and is ruled by the Moon. This is a very heavy card of settling down, where over time the lack of imagination and a certain dreaminess, will drag the current down to a mere evaluation of material things. Yet, this current comes from the Moon being in Taurus, the sign of her exaltation;making the best of the Lunar qualities inherent. Being a Six, the solar qualities have fertilized her creating a balanced system for the time being. Much like the balance between the Gravitational pulls of both Sun and Moon and Earth reach a point of Stabilization where the tides are neutral on the Earth's ocean. But as on Earth, this is temporary and soon change is coming in your life currents. Giving credence to the statement, " Success is a temporary respite on the path of labor.". All in all, the sixes are a very much appreciated relief from the Severity of the fives, but for the living matter, permanence is constant change, only nonliving things reach a seemingly permanent static environment. The difference between carbon atom based life and carbon atom purity as a diamond is seen here. Diamonds are dead and cannot regenerate, where as carbon atoms in the form of organic matter can.
