What is numerology

It’s a type of divination (fortune telling).


Divination is the attempt to foretell the future or discover occult knowledge by interpreting omens or by using paranormal or supernatural powers. The list of items that have been used in divination is extraordinary. Below are listed just a few. Many end in 'mancy', from the ancient Greek manteia (divination), or 'scopy', from the Greek skopein (to look into, to behold). Most forms of divination rely on magical thinking, apophenia (finding meaning in meaningless patterns), and pareidolia (seeing distinct forms in vague and random patterns).

It is a fun and interesting way to try to explain and understand the world and our lives. However, like any other religion, mythology, belief system, etc., I don't take it seriously.
