Explanation:

In my book, I use the term The Burden Level of Name because when a name is incompatible with the birthdate, it will become burden to the name holder.

Using The Page of Life and Death, the level is determined by the nearest number on the other page. Look at the "Pages" below.

The name and birthdate is compatible when the values are on the Page of Life. When they are on different pages, they are incompatible. The greater the distance, the heavier the burden.

For example, if the value of the name is 17 (Life) but the value of the birthdate is 15 (Death), the burden level is 1.
