I've read a lot about the power of positive thinking, the power of prayer, the power of attraction, etc. They all seem to boil down to something similar; ask, and it shall be given. Have faith that you will receive what you ask for.
I thought it would be fun to play with pictures, to sort of send out these images to God and the universe as a way to ask that my book sells.
If you want to make your own images like this; it's easy. Just google "fun picture effects" and tons of free websites will come up.
