Each Esoteric Culture is centered on helping in betterly understanding the world.
In order to do so, proper models are provided for pigeonholing.
In order to interpret a whatever phenomenon, the best fitting model should be used in order to help by themself in understanding relationships between entities, since there are already been identified, analyzed and explained.
There are a lot of provided models. The best classification method is based on the number of elements forming the model.
Usually, a model is built on such a number of elements that is included in the Fibonacci Sequence:
n = (n-1) + (n-2)
the first numbers of the series are:
1 - 2 - 3 - 5 - 8 - 13 - 21 - 34 - 55 - 89 - etc
|2||Sky / Heart||Early-Heaven / Later-Heaven Sky||Nagual / Tonal|
Air, Water, Fire, Heart,
4 Element (5-1)
|5 Elements||5 Elements
4 limbs + body
|8||Astrology (Solar System),
7 Faults,/Virtues (8-1),
|13||Gregorian Calendar (13-1)
"Sun Tzu Ping Fa"
Major Arcana (21+1)
|34||"Art of Being Right",Schopenhauer (34+4)||"Sam Ship Yuk Gye",
36 Strategems (34+2)
Minor Arcana (55+1)
90 numbers (89+1)
|"Tao Te Ching",
81 verses (89-8)
Models should be used together, combining them.
In fact, the main property of Fibonacci Sequence is that the ratio (n+1)/n tends to φ (Golden Ratio) as 'n' increases. That is, using for analyzing the same matter 2 subsequent models (i.e. 5-Elements and Ba Gua), it makes to come out relationships (i.e. differences) that bring to "Aureal Section". One of the most famous example of this is Feng Shui
Adjacent Model Combination
Combining 2 subsequent model leads to relationship directly related to "Golden Ratio". A common example is Feng-Shui, in which "5-Elements" and "Ba-Gua" models are applied, providing an interesting mapping model.
