In numerology, life is divided into four great stages. Each has a Pinnacle, the opportunity of that time, and a Challenge, the lesson that comes with it. The reading shows all four, with approximate ages, so you can see which stage you are in now.
From birth to about age 27–35, depending on your Life Path. The Pinnacle shows what this time favors, the Challenge the lesson that comes with it.
The next nine years, when you build your adult life. A new Pinnacle and a new Challenge.
Another nine years: maturity and its harvest, with their own Pinnacle and Challenge.
From about age 45–53 for the rest of life: the Pinnacle and Challenge of the later years.
