What does Diamond Way Buddhism say about obstacles at times of becoming more conscious?

N. D. Walsch claimed in one of his books that at the point in time, when a person "switches gears" to a higher level of consciousness, it frequently happens that events occur, which you perceive as negative. I don't remember the exact wording, but AFAIR he wrote that when some major obstacle occurs it may be that the universe is testing - do you really want to achieve a particular outcome (then you will continue in spite of the obstacle) or do you just think that you want it, but in reality want something different (in this case you give up) ? I experienced situations, which support this hypothesis on several occasions: 1. Once I went to a very powerful retreat. I needed to travel several thousand kilometers by plane and several trains. One train got late, I had to spend a lot of time in the train station filled with drunk (and potentially violent) soccer fans and garbage, then another train had problems because there was a suicidal girl walking on the tracks. According to the train guard, there was a fight on one of the trains and they had to call the police. Those soccer fans were everywhere and they left smell of vomit in almost all train cars. When I arrived at my hotel, nobody was there, my mobile phone ceased to work and I had to go to a nearby bakery to call the receptionist and check in. I've been to that country before and all these things aren't typical (didn't occur in my past travels with such intensity). The retreat was indeed life-changing. 1. It happens quite frequently that a rain starts exactly at the same time, when I realize something important. Same with Skype: Often the connection is lost precisely at the moment, when I or the other person says something important/profound. 1. Often, I experience some major conflict with other people (incl. threatening them to call the police, if they don't stop), and then, some time thereafter, I have either a productivity peak or some important insight. Does Buddhism in general and Diamond Way in particular say anything about 1. whether emotionally intensive situations (usually unpleasant) are signs of growth and 1. how to get most benefit from them (other than suck it up and persevere) ?
