Just wanted to connect this thread here:
This is a great book. @Charlotteannun gives a wonderful over view of the Maha Parinibbana Sutta.
I also really enjoyed reading the essay/interview with Ayya Dipa. I attended her first samaneri ordination at the Bhavana Society. She was the first person I ever saw get ordained. I had the good fortune to meet her again years later after she had taken high ordination and was living with Ayya Gunasari. I was really shocked just a few years to hear that she had passed away. Her essay/interview in this book was done right before she died.
