According to the Abjad system of Isopsephy, the word Baháʼ has a numerical equivalence of 9, and thus there is frequent use of the number 9 in Baháʼí symbols. The most commonly used symbol connected to the number 9 is the "nine-pointed star"; there is no particular design of the nine-pointed star that is used more often than others. While the star is not a part of the teachings of the Baháʼí Faith, it is commonly used as an emblem representing "9", because of the association of number 9 with perfection, unity and Baháʼ.
