The teaching presented in this book is an edited transcript of a retreat given by Drubdra Khenpo Tsultrim Tenzin, Abbot of the Meditation School at Triten Norbutse Monastery, Kathmandu (28.12.2021 to 01.01.2022). Broadcast via video link from Nepal, the retreat was dedicated to instructions from the Mother Tantra of Yungdrung Bon on taking dreams as the path. Although this book has been made public following Khenpo's explicit wish, anyone who seriously wants to apply these methods must seek an authentic master and receive the authorisation and transmission in person. This will give the practitioner the ability to clearly understand the meaning of these instructions and connect him/her to the blessing of this lineage, thus ensuring their practice bears fruit.
