"Three Fathers and their generations, Seven conquerors and their armies, and Twelve boundaries of the Universe.
See now, of these words, the faithful witnesses are the Universe, the Year and the Man."
-Sepher Yetzirah

The top Right Tree of Life arrangement is based on a combination of the tarot numbers and strives for the most harmonious arrangement of all the numbers used to each other. The names of the Tarot cards were added according to their corresponding number attribute.  

The top left Tree of Life path arrangements are based on a geometric configuration of the astrological attributes and can also be seen in the Cube of Space section.

The ten Ideal Number characters, 0-9, corresponds with the ten character cards of the Tarot: 0- The Fool, 1- Magician, 2- High Priestess, 3- Empress, 4- Emperor, 5- Hierophant, 6- Lover, 7- Charioteer, 8- Courageous, and 9- The Hermit.

The twelve remaining double numbered Tarot cards, 10-21, coincide with the twelve Zodiac signs: 10-Taurus, 11- Libra, 12- Pisces, 13- Scorpio, 14- Sagittarius, 15- Capricorn, 16- Aries, 17- Aquarius, 18- Cancer, 19- Leo, 20- Gemini, and 21- Virgo.

The relationship between the Major Arcana and the Minor Arcana is the same as the the relationship of the Solar Cycle to the Lunar Cycle. The Major Arcana consists of two primary sets of consideration:  the ten major bodies in the Solar System and a twelve zone spatial division of space and time called the Zodiac.

The 56 Minor Arcana cards of the modern Tarot decks consists of two primary categories, male and female elements, with 28 cards each. These male and female sets each consist of two more subsets of 14 cards each: representing the four elements of Earth, Wind, Fire, and Water. The Lunar cycle, in turn,  has 28 days (male) and 28 nights (female) and consists of 14 waxing (male) and 14 waning (female) days.

The older Minor Arcana, a.k.a, the common playing cards, or gypsy deck, only had 52 cards; ten pips and three court cards. Although it is a different number than the present Tarot it still reflects Lunar relationships. There are 13 moon cycles in a year and 52 weeks in a year. The three court cards correspond to the three dimensional modes, cardinal, fixed, and mutable, and the three states of the Moon, new, partial (waxing & waning) and full.

The Tarot and the Tree of Life may have originally come from different approaches to teaching the same theories of Numbering, Naming, Imaging, and the Harmonizing of them within the Moment. I can certainly see how they had gotten married to each other in the first place; and I can see no good reason not to continue using them in conjunction with each other.

This is a basic demonstration of breaking the Tree of Life  down into its primary components; then reconstructing the pieces, from a present point of view, into a new vessel of a greater, more relevant, value to the modern mind than the  myriad of previous vessels.
