Your nickname comes into play again with the Minor Heart's Desire Number. You calculate it the same way you do the Heart's Desire Number, only this time, you will be working with the vowels in your nickname. Even if you don't change your name at all when you introduce yourself to people, odds are you do leave out your middle name or make some kind of adjustment along the way.
If your full name is Mary Elizabeth Lyons and you just go by Mary Lyons, you would calculate using the a,y,y and o.
1 + 7 + 7 + 6 = 21; 2 + 1 = 3
Mary's Minor Heart's Desire Number is 3. To contrast it with the Heart's Desire number, let's do that calculation using all the vowels: a,y,y,i,a, and e
1 + 7 + 7 + 6 + 1 + 5 = 27; 2 + 7 = 9
The difference is clear. Mary's Heart's Desire Number is 9, her Minor Heart's Desire Number is 3. These differences are significant because the minor number can either build up the qualities of the major, it can appear to contradict it, or it can provide insight into what you really want out of life that the major number leaves clothed in mystery.
Mary, for example, has a major Heart's Desire number that makes her champion humanitarian causes and view the world in a very idealistic way. The minor 3 may make her appreciative of the aesthetics in life as well as the things that entertain the senses. Someone with this combination of Heart's Desire Numbers may be the the type that seeks to solve the world's problems in a creative way, using emotional images to evoke thought. She might be passionate about issues revolving around food like GMOs or pesticides, but she would be more prone to make a documentary about her cause of choice than to attend a political rally in support of it.
Remember that you should consider Y in your calculations if it is the only letter than functions as a vowel in your name (Like “Sy”) or if it is the only letter in a syllable that makes a vowel sound (like in our example, “Mary”). If you need a refresher on the difference between consonants and vowels, you can refer to the section for The Heart's Desire Number for guidance.
Over time, our sense of identity changes. Many of us had nicknames when we were children that we don't like to use as adults. This is where Kimmy Becomes Kim and Mikey becomes Mike, or Mick. The name that we use to identify ourselves has it own resonances and is therefore a legitimate consideration in our numerology chart.
“Well, what if I have no middle name to begin with and I simply go by my name, Mary Lyons?” In that case, you can simply plug your Heart's Desire Number into your Numerology chart a second time and read the interpretation as it applies to your minor expression. You don't have to do any more math. For the rest of us, doing the calculation is the next step. You can refer to a letter value chart or simply use the calculator on this page and tally up the vowels in your nickname.
