Quoted By:
"In the Torah, the numbers 1 and 4 are deeply related. Their ratio is considered the most perfect, as it the ratio of words to letters of God’s essential Name, Havayah (?-???). For this reason, Havayah is called the Tetragrammaton, indicating that it is a name consisting of 4 letters. This ratio is hinted to in the two-letter Biblical word “mist” (??), whose two letters equal 1 and 4 respectively.
One of the models used to relate the four letters of Havayah is that of a family comprising a father, mother, son, and daughter, which correspond to the four letters of Havayah, in order. Indeed, the minimal requirement for fulfilling the first commandment of the Torah “Be fruitful and multiply,” is to bear at least one son and one daughter. Another well-known Kabbalistic model related to Havayah in the same way is that of the four Worlds: Emanation (atzilut), Creation (beri’ah), Formation (yetzirah), and Action (asiyah).
Foregoing the happy-unhappy nomenclature let us adopt one that is more suited and that carries deeper significance. The number 1, of course, represents singularity, so let us call the numbers that reach one according to the algorithm defined above “singular numbers.” Following our identification of the number 4 with the ideal family, let us call the numbers that reach 4, “family numbers.” So, all integers are either “singular numbers” (or sn, for short) or “family numbers” (or fn, for short).
Now let us look at the meaning behind our choice of nomenclature. To be “singular,” or “1-oriented,” from a spiritual perspective, means that one’s consciousness is focused solely on God the Creator, who is absolutely one. To be “family” or “4-oriented” means that one’s consciousness is primarily focused on one’s mission on Earth, represented by the universal commandment of “be fruitful and multiply,” i.e., bearing a family."
