This series of lectures is a comprehensive compilation of Watts teaching on Buddhism, Zen, Hinduism and Taoism. Plus there is also the humor of his one-of-a-kind philosophy based on years of studying the Eastern religions and philosophy. As an Anglican Priest he also has great insights into Christianity. Once you've listened to this you've got everything Watts had to give. Although like me, you may find yourself drawn to rehearing these humorous and insightful talks over and over again.
I've been waiting a long time for a good audio version of Hsin Hsin Ming and so I was very happy to discover this excellent overview of this key text in Zen literature. The author does a good job of doing a line-by-line explanation of the poem. I especially appreciated his use of the variety of translations in this commentary. He showed that there is more than one way to interpret the text. As with all things Zen, listeners are free to reach their own conclusions.
I've studied Vedanta for decades and did not know that there were any recordings of Swami Vivekananda. Assuming this is authentic -- and it certainly sounds as if it is -- this is an amazing historic recording that will be fascinating for anyone interested in harmonizing the world's religions.
If you're read the Epic of Gilgamesh, The Odyssey, Journey to the West, then you'll have to read this too. It's a great story with great lessons, very enlightening indeed. Great performance and very clear explanations. This is a must have in your collection of epics.
