Within Loseling College, there are 23 or 24 khangtsen, and he belongs to Tsawa Khangtsen; within that there are an additional three mitsen. He explains that each khangtsen has its own rules and ways of doing things and gives several examples. He gives an overview of the major religious festivals, like Saga Dawa, and the different positions of monastic officials within the khangtsen, college, and monastery in general. He follows a mental map of the monastery, describing the buildings and sacred sites, providing their names and stories about the meanings of their names.
