Yeah kind of getting out of hand these days... We're becoming a rediculously superstitious group of people, quite alarming to watch how this " R' yeshayala of kerestir " phenomenon is exploding.. he's apparently the new version of R' shimon bar yochai or wtvr.. thousands of people flying across the world to his kever, full page ads if him wherever you go.. not sure if it's just simple minded people or it's some money making scheme by some marketing group.. but it's very disturbing on many levels.
Any segulah that comes with a men/friends getaway, good food and you can claim it's purely Ruchnios will always sell good. Granted, there are plenty amazing factual stories of people who had yeshuas there, but a good trip al taharas hakodesh will always draw lots of people, same with Meron. Good to keep in mind when you become concerned that we have become to superstitious.
