How does numerology fall into place with the bible?

Also, what about other things in the occult. like white magic, telepathy, lucid dreaming, mystiques, tarot cards. I just don't understand. If your intentions are good, then how can such things be condemned by the bible. If I was born under these cosmic forces (according to numerology) & that is what makes me who I am then how can the study of such be evil. Please give me any insight.
