There is a wonderful video about the life and teaching of Nisargadatta Maharaj entitled "Awaken to the Eternal." You can buy it on DVD, but it is a bit pricey. However, someone has posted it on YouTube. The video is very watchable and quite amazing. Watch it. Enjoy it. Learn from one of the greatest teachers ever.
The first of six parts is below. You can head over to YouTube for the remaining 5 videos. Enjoy!
