6 is considered the most harmonious of all single-digit numbers and the most compatible with all the other numbers. The most important influence of the 6 is its loving and caring nature. Often called the Motherhood number, it is all about sacrificing, caring, healing, protecting and teaching others.
[as an aside note, 6 and 7 are also most often missing from a name, making them the most frequent karmic lessons for people in general to learn.]
The 6 is full of sympathy, and its sense of justice is well developed — when a 6 perceives injustice, it will sacrifice all its time and effort to set things straight. Almost always favoring the underdog, a 6 would never purposely hurt anyone, especially those less fortunate.
The 6 is idealistic, trusting and easy to take advantage of, which can produce devastating results. A 6 carries its heart on its sleeve and expects the same from others. The role of counselor and advisor comes naturally, and many will come to cry on a 6’s shoulder or to seek down-to-earth wisdom.
No number is without weaknesses and faults, but the 6 is actually the most harmonious and stable among the nine single digits. Yet, perhaps for that same reason, when the 6 falls into discord and disharmony, it becomes possibly the most destructive and dangerous of all numbers. Beware of a cynical, jaded, or angry 6 – s/he is like a merciless wolf in sheep’s clothing.
