I asked before about meditation retreats but asking again for clarity from those that have done 7 days to 30 days.
Does it improve your ability to relax? Disconnect? Zone out or zone in? Does it improve your patience? Improve your ability to not care?
I have no idea what your point is. Most Thais have never been there. They live in Thailand. I know people who have been to Phuket 30 times. They don't live in Thailand. Living in Thailand has nothing to do with Samui or KPN.
