From the book preface:

"The Treasury of All Blessings is a collection of short guru yogas connecting us with the great Tibetan Kagyu masters and thus enabling their qualities to emerge within ourselves. Khenchen Konchog Gyaltshen Rinpoche composed these texts for daily practice in the years between 2008 and 2021. Under his guidance, the practices were rendered into English, and Chinese and German translations were also created. Although they are kept very concise in order to fit into the busy daily lives of today’s practitioners, the guru yogas are very profound and inspiring. This impression was further confirmed by listening to Rinpoche’s explanations on them.

Our intention was to compile all the guru yogas into one booklet, concluding with a special dedication prayer of Drikung Kyobpa Jigten Sumgön. When we learned during the preparations for this publication that His Holiness, the Drikung Kyabgön Tinle Lhundup recently had written a long life prayer for Rinpoche, we decided to expand the booklet and also add this and a long life prayer for His Holiness by Khenchen Konchog Gyaltshen Rinpoche. This compilation is thus a true source for the practice of guru devotion."
