The number thirteen possesses a great mystical significance. In Christianity, Guatama, Buddhism, and Shiite Islam there are twelve followers and one master. 12 +1=13. Spiritual ignorance or blindness causes the superstitious fear from the number 13. Hotels floors exempt the 13th floor, and some hostesses will refuse a party of thirteen. This is a shout out to the number thirteen for when used correcly can bring great wisdom.
