This is the fourth lecture in the lecture series that is available for sale. You can choose to purchase these lectures as downloaded mp3 files or as DVD video through our store. But the least expensive way to hear the lectures is to access them from inside this eLearning course.
The first seven lectures are free so you can see the quality of what we are offering, but beginning with chapter 7 you will need to purchase the lectures if you want to have access to them. Go to Chapter 7 and click on the "Purchase access to the audio and video lectures" link. You will be taken through PayPal where you can purchase the lectures.
These lectures cover the entire chapter. The summary lectures also included in the online course summarize just the high points of the lecture.
