Behind this axiom lays the mathematical foundation of all life - the science of numbers and vibrations.

Reducing things to their most fundamental:
Twenty-two numbers (1 to 22) make up 22 vibratory frequencies (the 10 planets* and 12 zodiacal signs).

Note to Reader. Astrologers know the sun and moon are not planets, but refer to "10 planets" for convenience.

The vibratory frequencies of these twenty-two numbers transmit their resonating energy to all life.

Be it a musical note, an alphabetical letter, a diamond, an electoral victory, a new car, a hockey team, a city, a peace treaty, a world organization - all are keyed to resonate to the vibrations of one of the twenty-two numbers - the ten solar system planets and the twelve zodiacal signs.

The Law of Correspondence.

Thus does a scientifically measured astrological map of the heavens, (astrology, the Golden Key, the masculine polarity of occult science) indicate the correspondence between activity in the sky and activity on earth.

The tarot, the Silver Key, (the feminine polarity of occult science) too, is an exact, positive science.

C.C.Zain
The Science of Vibration.
"Right here it should be emphasized that the Hermetic System of Vibration, as determined through using numbers, is quite unrelated to any system of numerology.

Numerology, new systems of which are being devised each year, is a method of divination. And as divination by numbers is one of the four functions of the tarot, nothing here is said in disparagement of numerology."
