I just found this amazing website, Thinking is Causative .com  There are lots of FREE e-books to download there , including my all time favorite book, The Edigburgh Lectures on Mental Science, by Tomas Troward.

“The  Universe is governed by Law – one great Law. Its manifestations are multiform, but viewed from the Ultimate there is but one Law. We are familiar with some of its manifestations, but are almost totally ignorant of certain others. Still we are learning a little more every day – the veil is being gradually lifted.” (From “Thought Vibrations” by William Walker Atkinson)
