Hey Friends,
can someone recommend a meditation teacher or retreat center in Sri Lanka.

Some real meditation master would be nice... but hard to find I guess.  And good English would be helpful.

I already spend some month in monasteries in Thailand and Burma, but I was very disappointed by the teachers there. In one retreat center in Thailand where I stayed for 3 months, I had a western teacher who admitted after the 3 month that he did not make it to stream entry so far and did not have any concentration skills.

In another well known monastery in Burma (Myanmar) where I stayed, the only question the teacher (a Burmese monk) was asking me every day was: "for how long can you stay with your breath ? "... and whatever my answer was on that day, the monk replied: "you should try to make more".   I tried to squeeze more teachings out of him, without success.

I'm really trying to avoid more of those experiences, but despite my research back than, I ended up in those places.  Therefore, I hope to find some recommendations here.

​​​​​​​cheers

I was not there personally but have some good references from people who were meditating under guidance of Pemasiri Thera.

Hey, Thanks a lot, looks promising.

I found the internet site:

and the youtube channel:

Do you know how the teaching for foreigners is done? Is there someone who is translating, or is there a teacher who is speaking English?
Seems like Pemasiri Thero is not speaking English.

I only know that they teach English speaking people, so I guess they must have a translator. But for details you should probably contact directly the center.
