What Does “4” Mean?
First, we’ll look at the significance assigned to “4” by two different numerological sources. Second, and more importantly, ask yourself if “4” or any of the intermediate numbers above have any special significance to you.
“4” (the tetrad) according to the Pythagoreans:
“Anatolius reports that it is called ‘justice,’ since the square (i.e., the area) […] is equal to the perimeter”
“It is the prerequisite of the general orderliness of the universe, so they everywhere called it a ‘custodian of Nature.'”
“Everything in the universe turns out to be completed in the natural progression up to the tetrad”
“The tetrad is the first to display the nature of solidity: the sequence is point, line, plane, solid (i.e. body).”
Examples of things that are divided into four parts:
“four traditional seasons of the year — spring, summer, autumn and winter.”
“four elements (fire, air, water and earth)”
“four cardinal points”
“four distinguishing points – ascendant, descendant, mid-heaven and nadir”
“Some say that all things are organized by four aspects – substance, shape, form and principle.”
“4” according to Edgar Cayce:
“In four, it makes for the greater weaknesses in the divisions…four being more of a division and weakness” (reading 261-15).
“In four, we find that of a division – and while a beauty in strength, in the divisions also makes for the greater weakness” (reading 5751-1).
Does “4” — or do any of the other numbers above (e.g., 22, 49, 76, 103) — have any special significance to you?
Think about your own preferences and personal experiences: lucky numbers, birth dates, music, sports, and so on. Maybe your favorite football team is the San Francisco 49ers, for example.
Also think about associations you may have picked up from your culture, your religion, or society in general.
If you have any interesting insights about the number 4, or any of the other numbers above, please leave a comment!
