A great place to get material on this body of work is Ester Hicks website.
If you really resonate with the work, there is an email list where you can sign up for daily Abraham quotes. These emails are entertaining, interesting, and tend to help to start the day on a high flying disk.
Books, DVDs, and other Abraham/Hicks resources can either be purchased on the Abraham/Hicks website, or through Amazon.com.
There are also many YouTube videos that you can find by searching for Abraham on YouTube.
It is difficult to pick a "favorite" book. You can review them here....
