The Horse Shoe 
A symbol of fortune
“Collecting the positive energy and eliminating negative energy.” 

“The Horseshoe” symbolizes luck or fortune. When westerners see the horseshoe, they will remember the cowboys referring to the sense of traveling. Last but not least, there are seven holes in the horseshoe, and the seven is the symbol of a lucky number in general. Furthermore, there is some belief about hanging horseshoes at the door in order to collect good fortune which does not let the good fortune spill out of the home.
