Isaacrpgr

I just came to a sort of conclusion,or mo0re so a realistation whys there so many divination methods,one to cover each aspect of the questions(sometimes more than 1 method for question)

What-Numerology
When-Astrology
Why-??
Who-??
How-Tarot,Runes

I don't know of many divntation methods,so why don't ye fill in the blanks? or suggest where the suggested methods could also fit in?
