There are certain words that are more familiar to most people and to the human consciousness. For example, if you ask somebody to give you a number from 1 to 10 right off the top of their head, chances are the number 7 will be chosen more often than any other number—often dwarfing the next choice. Therefore, using the number 7 in a book title such as “The Seven Ways to Improve Your Relationships” or “The Seven Spiritual Laws of Success” is utilizing the most common and familiar integer of the first 10. You are therefore vibrating with the familiar and harmonizing with your reader.
