From the Teaching Company's "The Great Courses" series and also part of the "Great World Religions" series. I found this an interesting and entertaining introduction to Buddhism and greatly enjoyed Prof. Malcolm David Eckel's presentation. Each of the 12 lectures were 30 minutes long and a course book provided an overview of each of the lectures along with suggested outside readings and glossary.
These are wonderful for passing time in the car and at the gym. I like to listen to them while doing my walking.
This is a wonderful price from the original $90.00. It is also available for $20 on CD or DVD, with shipping of $10. In those cases the course guide is a paperback. With the audio download it is a pdf file.
I also have the other courses in the Great World Religions series and am excited to start on Hinduism next (although I am wondering, if I should have done it first.)
