It seems most places on the net you go, many people will find these to be interchangeable. I have to say I find this rather disconcerting, because if you look at the practices of the 2 traditions, they are really quite different. I know that Zen came about when Ch'an was brought over from China, but the practices were adapted to suit the needs of the people which they were brought to, and so are very different from where they originated. I have never heard of zen practitioners doing nianfo, or chanting of the 88-Buddha's names, which are common practice in Ch'an. Who knows, maybe it is just me......
What about Caodong/Soto?
Soto tends to put more emphasis on Dogen than the Buddha. Many Soto teachers don't believe in rebirth either.
Actually, the mark in "Chan" isn't an apostrophe, it's a tone mark, indicating that the word is pronounced in the second tone. It's pronounced "Chan?", as if it were a question.
Two Soto priests were Banned on esangha for their anti rebirth stances.
QuoteTwo Soto priests were Banned on esangha for their anti rebirth stances.I am familiar with this, but I am not sure that someone's willingness to argue a point represents a broadly accepted belief in Soto, or even a strong personal belief in an individual. As I mentioned, I haven't seen anything in Dogen's writings or in the comentaries of other Soto patriarchs that would suggest a disbelief in rebirth, although Zen does promote a non-attachment to views/opinions. Just as some Priests molest children, the Catholic church doesn't promote pedophilia, what a priest or two says on an internet forum, regardless of how prestigious it may be, doesn't, in my opinion, present some profound difference between Rinzai and Soto or Ch'an and Zen and Soen and Tien.I think what differentiates Ch'an and Zen more than anything is how preceding religious/philosophical frameworks, like those of Confucianism, Taoism, and Shinto, may have affected the language used to make Buddhism more culturally relevant and available in each of the different societies.
