From Book - Approaching Vajrayana - David Chapman
It is true that you need to get along reasonably well with your sangha (Buddhist community). However, for Buddhism to be effective, it needs to undercut your basic assumptions about life—your “reference points.” An excessively comfortable group, which constantly validates your reference points, is an obstacle.
A sangha should be irritating. It should include many people whose experience and understanding of life is quite different from yours. They will rub you the wrong way, because the things they take for granted without thinking about them are different from the things you take for granted without thinking about them.
