What is the use of knowing the Abjad value of one's name? How can I determine if the Abjad value of my name is good or bad or what does it signify?
The only thing I can recommend is the Wikipedia's entry related to the Abjad Numbers and their meaning. After you'll read the article on Wikipedia, you'll understand what is the importance of these numbers and how you can calculate yours, if the software allows it. Access the Wikipedia link below. If you want it in another language, use the menu on the left.
