Simply put, crossing refers to spiritual works that cause harm or bad luck, while uncrossing refers to works that reverse it. There are a number of products sold that are used to aid in putting an end to crossed conditions, particularly when used in conjunction with one or more of the psalms. For example, products such as uncrossing crystals, oils, sachet powders, and incenses are believed to be particularly effective when used in conjunction
with the 37th psalm. The word cross is virtually synonymous with the words hex, jinx, and a curse.
