Note: I am no teacher of Vipassana and merely a student (that too not advanced), so my thoughts should be taken with a grain of salt. The folks running the course do have a screening by asking you certain questions in the enrollment form and they do ask you to talk to someone if you are confused or concerned about any question. It is not a strong screening but screening nonetheless. How effective it is, I don't know and it also comes down to how forthcoming the student is in clearly stating his/her condition. Having said the above, people do experience intense emotions like you mentioned as I observed first hand. My take based on what I learnt in the course and afterwards is that throughout life since we are born, we experience life and it builds up certain kind of emotions in ourselves. Depending on who had what experience in life, the build up can be very strong. Vipassana attempts to rid you of the emotional build up that one has accumulated. The act of crying or shouting, or anything else is an act of getting the emotion out of the system and be left with a cleaner state of mind. How long the emotional outburst will continue will depend on how much one has accumulated in life. I would summarize this as - In order to fill a cup with afresh, you must empty it first. You can't fill an already full cup. One may also want to read U G Krishnamurthi. One of his quotes that I really like is `When the movement in the direction of becoming something other than what you are isn't there any more, you are not in conflict with yourself.` another way to interpret this is that emotional build happens when you action is in conflict with your inner self and over a period of time, the build up keeps growing resulting in problems (I have had emotional build ups that I have worked very hard to get rid of).
