About Omamori:

Omamori is generally translated as an amulet, or good luck charm, and comes from the Japanese word mamoru (守る ), meaning to protect. The amulet contains prayers written on paper and sealed inside small pouches of embroidered brocade. The pouch is usually rectangular with a short strap to attach to your personal items. Many shrines and temples take pride in the designs of their omamori and incorporate unique details and colors in the design. Ideally, the owner of an omamori is supposed to carry it with them in order to both protect against bad luck and usher in the good.
