I've read some of his books about primitive Buddhism. I didn't know what was the original Buddhism before reading them. I believed all Buddhism sects was the same.
The hall I went today was very silent. No one was there but a stuff. There were lots of books there. They looked very expensive. I checked one of them on the web and the prices were from ¥20,000 to ¥180,000.
I want to know more about original Buddhism. I can read some books from the library, so I'll go there to read books sometimes.
