Part of the Supreme and Unsurpassable Mahamudra of Liberation is available online in Chinese. Arrangements can be made to view the secret part in Chinese at several temples and Buddhist institute in the USA. Although the text of the Supreme and Unsurpassable Mahamudra of Liberation is not available yet in English, some have been given permission to read from a preliminary translation of the text at some locations and on ZOOM.
A preliminary translation of a very essential part of it is available to the public and that is the Buddha-dharma provided by H.H. Dorje Chang Buddha III as “The 128 Evil and Erroneous Views.”
