Buddhism really surprises me. I have not read so much about it. Gautam Buddha was born in Nepal, then he got his divine knowledge in India and preached in India and may be Nepal too. But Buddhism is followed in the Mongolian countries like China, Japan, etc. Whatever Buddhists are there in Nepal and India are originally from elsewhere. So how come Buddhism spread elsewhere and not in Nepal and India. And what religion did these countries practice before Buddhism? How did Buddha communicate with these people?
