Vipassana is really a life changing experience, you live like a monk for 10 days, you eat and stay on the donation of others(Mr. Goenka said don't donate as if you stayed for 10 days in a hotel you donate for others and others donate for you).

Meditating for about 11 hours a day.
For the 10 days, you practice noble silence( no eye contact, no physical touch, and no gestures).Your phones, cameras, reading writing materials are kept in a locker and you just live in your present one of the best thing that I ever experienced.I thought meditation will be easy after completing a high altitude trek but trust me your mind keeps wandering between past and future and trying to control it is the toughest part.
Things that I really liked about Vipassana they don't ask you to blindly trust everything or ask you to follow any religion or its beliefs, you can meet people from all the religions here.If you like the practice you keep it with you or you can lay off the practice after 10 days.Course purely runs on the donation basis and you can donate as you wish.Finally, the centers are very well maintained and you get a proper environment for meditation throughout the course.
