According to the documentation provided in “Healing Codes for the Biological Apocalypse“, Dr. Joseph Puleo was introduced, through an open vision, to the Pythagorean method of numeral reduction. Using this method, he discovered the pattern of six repeating codes in the Book of Numbers, Chapter 7, verses 12 through 83.
The Pythagorean method is a simple reduction method, used to turn big numbers into single digits. The values of all digits in the number are added up. When after the first addition the number still contains more than one digit, the process is repeated.
