The 9 Pointed Star is also known as the
"Enneagram", which comes from the Greek word ennea
(nine) & grammos (to be written or drawn).
The Baha'i faith has reverence for the number
9 for various reasons. It is considered by those
who are interested in numbers as the sign of
perfection, that is, being the largest single
digit number, nine is considered a symbol for
completeness and wholeness. Also it is the
numerical value of the word "Bahá?".
The symbol can also represent the nine great
world religions: Baha'i, Buddhism, Christianity,
Hinduism, Islam, Jainism, Judaism, Shinto, and
Sikhism.
In the Christian faith, the nine-pointed star
symbolizes the nine fruits of the Spirit listed
in Paul's Epistle to the Galatians (5:22): love;
joy; peace; patience; kindness; goodness;
faithfulness; gentleness; self-control.
