The teaching of Ven WA was very controversial.
He passed away few years back but his main disciples are making the Buddhas teaching even more controversial.
One of them is Ven. Walasmulle abaya. He got a very strong following in the West. Another monk is the one who brought up the idea that Buddha was born in Sri Lanka.
I have listened to many of those monks and my opinion is that their contribution is minimal considering the damage they make to the teaching.
Now there is a strong opposition is gathering in Sri Lanka towards these new interpretations.
