One popular application of numerology is the study of the Loshu, also known as the Magic Square. The Loshu is a 3×3 grid that contains the numbers 1 through 9, with each number appearing only once. According to legend, the Loshu was discovered on the back of a turtle in the Yellow River in China more than 4,000 years ago. The numbers in the Loshu are believed to have significant symbolic meanings and can be used for divination and fortune-telling.

A course in numerology and the Loshu typically covers the history and theory of numerology, including the significance of individual numbers and how they relate to personality traits, life path, and destiny. Students may also learn about various techniques for using numerology for divination and forecasting, including the use of the Loshu. The course may include practical exercises for calculating and interpreting numerological charts and using the Loshu for divination. Overall, a course in numerology and the Loshu can provide a fascinating exploration of the ancient wisdom of numbers and their potential to unlock the mysteries of the universe.
