Desung is a Tibetan term for "bliss protector" or "harmony protector" and it is both a branch of the Dorje Kasung and a specific role a Dorje Kasung may fill. As a role, someone may be assigned as the Desung for a program, retreat, or in an ongoing way for a retreat center or Shambhala center.
In an Interview with Desung Arm Commander Debbie Coats in May 2009, she describes the roll of the Desung corps as "...choosing to step in to situations that are uncomfortable or perhaps frightening. In our community desung are kasung who focus on issues of health and well-being or conflicts. So if people are in distressing circumstances or conflicts are occurring, for example between members in a Shambhala group, the desung role is to notice what is happening and make sure that the situation is addressed and related to in the most appropriate way."
