Capstone

The capstone is the last letter of your first name, along with the number it carries in the Pythagorean chart. It describes how you tend to finish things and bring efforts to completion. It pairs with the cornerstone, which looks at the first letter instead.

How it's calculated

  1. Take the last letter of your first name.
  2. Look up its number using the Pythagorean chart.

Example First name John: the last letter is N, which carries the value 5. The capstone is N, value 5.

Common questions

Do I reduce the capstone to a single digit?
No. It is always a single letter value from 1 to 9, taken straight from the Pythagorean chart without any addition or reduction.
How is the capstone different from the cornerstone?
The capstone is the last letter of your first name and points to how you finish things. The cornerstone is the first letter and points to how you start.
Is the capstone a core chart number?
No. It is a minor detail that adds nuance about follow-through, rather than a core number like the destiny or personality number.
