I attended a 10 day course earlier this year. Before I went, I had read these stories, and admittedly, I was afraid I'd, at the very least, be terrified by what came up in my mind. But that's not what happened. Following their simple instructions, my mind became quieter, calmer, and sharper. I had more control over my fear response. It ended up being a great experience, and I'd recommend anyone interested in one of these courses to go for it.
I was also concerned about the environment. I was thousands of miles away from anyone I knew in a strange place and different country. We were asked to hand over our phones, reading material, journals. We were asked not to speak to anyone and to avoid any form of communication. But this was all to benefit our meditation. We were given a space for several days to really focus on ourselves without external distractions. The day our silence was lifted, you really got to experience just how much talking to another person can disturb/distract your mind.
