Beth,
I have listened to stuff by Eckhart Tolle. Very good explanation of what is happening all around us. Deepak Chopra has many audio books out too. I find his books interesting to listen too also. There are others as well.
~ SOUNDS TRUE: Wisdom for the Inner Life ~ go to this website and there is a wealth of audio to choose from. You can order on line or get ideas and go to your local book store and see if they have something you are interested in.
