Rhythm and number underpin our lives, from the days of the week and the times of the day to the number of letters in the alphabet. But do we ever stop to consider the deeper meaning behind these every day realities? In Uncovering the Secrets of Time and Number Wolfgang Held offers a fascinating exploration of this question. He looks at why there are seven days in a week and how each day resonates with different soul moods in the human being, for example why Tuesday is a good day for making mistakes and why Friday is the day of beauty and creativity. He also explores the qualities of numbers from one to thirty-one, explaining how many things have an inherent number attached to them: one sun, two parents, three meals a day, four seasons. The practical insights brought together in this book can help the reader become more conscious of their relationship to time and number, allowing them to organise their lives in a harmonious way.
