If you watched part 8, you see that I’ve cited a few sources that I used to break down these subjects. As explained in the video, some of these books are hard to come by, but there are free pdf’s that people can download to read the content themselves. I have attached some pdf’s of these books for those who may lack the resources to buy these books. Below are the pdf’s of the sources used in this video. I hope this helps all who seek it. Click each image to get the pdf. Be blessed
