Edgar Cayce taught that numerology and astrology does map our future or fate. However, we do posses the ability to make our numerology and or astrology profile null and void. Our dreams also tell of our future and of our fate. In the once out laud hawaiian religion, It is said and documented that a great Ka Hana could not only tell the future but change it by controlling their dreams. It was a great Ka Hana who told of the white men who would come to visit and allowed it.
I say if you do nothing today - the sun will still rise tomorrow. What will be, will be.
If however you do something today - when the sun rises the morrow, what will be will have a twist to it.
