"The 33 is the most influential of all numbers. It is the Master Teacher. The 33 combines the 11 and the 22 and brings their potential to another level. When expressed to the fullest, the 33 lacks all personal ambition, and instead focuses its considerable abilities toward the spiritual uplifting of mankind. What makes the 33 especially impressive, is the high level of sincere devotion. This is shown in its determination to seek understanding and wisdom before preaching to others. The 33 in full force is extremely rare."
