A fantastic center and a fantastic experience. Donation based fee.
The center gives you a unique opportunity to try out a life where only you and your mind exist for 10 days. All food is prepared for you at specific appointed times during the day. You may not communicate with other participants, neither are mobile phones, books etc. allowed. Thanks to this, you are able to devote all your time to meditation (vipassana), which is taught progressively during the course.
If you life a typical urban, stressful and career focused life, combined with that somewhat uneasy feeling that "this can be it.. there has to be more to life then doing this thing (i.e. job) over and over until death", I cant emphazise going to this place enough.
Entering the depths of your mind through hours and hours of meditation, insight of behavioral patterns that must be broken to start to live life again will come. This, along with an amazing tool to do just that, is just mind blowing and SO worth 10 days of your life. So skip the Mallorca trip and go for this instead.
Although, I must warn you, it is hard mental work and some days will be rather harsh. However, it'll get better along the course.
Good luck !
