I read a lot of books, watch DVD and listen to audio books on the law of attraction and the power of positive thinking. I also use positive affirmations and visualization techniques through meditation and before I go to sleep.
Here are some of the authors I like:
(Just Google him, he has a lot of audio and text you can download for free)
(They have a lot of good DVD's and audio recordings that I buy from their website. They speak about the law of attraction-"That which is liken to itself is drawn.")
(She has a lot of good books and she uses affirmations A LOT. That is where I have gotten mine from and she speaks mostly about love and forgiveness of yourself. She uses affirmations to help cure disease and has done it for herself).
(He speaks more from a spiritual side of things, but he focuses on the power of positive thinking and being happy.)
Dr. Wayne Dyer
(He has a lot of great books, "Excuses Be Gone" or "The Power of Intention" and he has a great movie I recommend anyone watch it is called "The Shift." He focus on the power of your thoughts and the cause and effect of the way we think and what we believe in.)
(He has the books the "The Science of Getting Rich" and "The Science of Success")
All of the authors are really good, it just depends on how you receive the message. I have listened to a numerous amount of books, authors, etc that all focus on the power of positive thinking and the law of attraction. The funny thing is the message of all of these authors in the end is the same, but I have realized some people hear it better or understand the message from one author over another even though they are saying the same thing. I hope this helps.
