In numerology, a number represents certain energies. It is the interpretation of those energies that a person says is the meaning of the number.

In that sense, the numbers 3 and 21 are similar. When 21 is reduced to a single digit, which is done to obtain its base essence, then the result is the digit 3.

Both 3 and 21 tend to express themselves creatively, but they do have differences. 321 is more a home and family number.

Here are three articles, one for 3, another for 21, and a third for 321 dedicated to the meanings of those numbers, respectively.
