One of the worst forms of cursing is envy. This is because it is often done unconsciously by others. Envy is a natural human feeling and its human nature to compare oneself to another and be envious of what someone has accomplished or possesses over what you have yet to accomplish or possess. Therefore envy has no boundaries.
Wash your body with the soap in the bath/shower to protect yourself from envious people and to put a stop to their envy while praying or meditating on your desired result.
