Alomancy, also known as halomancy, is the practice of divination with salt. 
In many traditions, salt is associated with spirituality, cleansing, purity, balance, and protection. It is also known for its transforming qualities. Moon will use this particular energy to cast a reading in order to connect to the soul contract perimeters direction and ultimate path of purpose goal. Moon will interpret the patterns that your guides present to her in a similar way to how someone interprets tea leaves in a teacup reading after presenting your guides with specific inquiring questions that you are seeking more guidance on.
