What are teacher trainings with Chögyal Namkhai Norbu?

Teacher trainings with Chögyal Namkhai Norbu are retreats where candidates who want to become teachers of Santi Maha Sangha, Yantra Yoga and Vajra Dance present themselves to Rinpoche, or are presented to him by the international Yantra Yoga and Vajra Dance teachers. Usually the Vajra Dance candidates have to demonstrate a sequence of the dance and answer one or two questions asked by Rinpoche or the international teachers. If Rinpoche approves the candidates, they receive the authorization to teach, and a diploma signed by Chögyal Namkhai Norbu (see previous question).
