In addition to the German text, here something written in English.
Yongdzin Rinpoche, Lopon Tenzin Namdak, the greatest living master of Dzogchen within the Bonpo tradition of Tibet, will teach a retreat in Germany on the ancient text entitled “The Seven Mirrors of Dzogchen,” from the cycle of the Namkha Thruldzöd, “the Magical Treasury of the Sky,” by the enlightened Dzogchen master Drenpa Namkha. Having been a master of Dzogchzen meditation practice in both the Bonpo and the Buddhist traditions, and completely rejecting all narrow sectarianism, Drenpa Namkha was among the Twenty-Five Disciples of Guru Padmasambhava in Central Tibet in the 8th century of our era. After having concealed many Terma texts himself dealing with the practice of Dzogchen, this master composed this short text distilling the very essence of all these teachings.
Beginning with the qualities necessary in a master and in a student, the view, meditation, conduct, and result of Dzogchen practice is discussed in lucid detail, as well as providing descriptions of higher states of consciousness and practices in preparation for the Bardo experience after death. During the retreat and based on this text, Rinpoche will provide instructions for the practice of Dzogchen.
THOUGH A MAN BE LEARNED
IF HE DOES NOT APPLY HIS KNOWLEDGE
HE RESEMBLES THE BLIND MAN
WHO WITH A LAMP IN THE HAND CANNOT SEE THE ROAD
