H.H. Dodrupchen Rinpoche is the supreme leader and sole holder in the entire world of the complete Great Perfection Longchen Nying-thik Dharma. All of the Longchen Nying-thik lineages practiced in each of the major monasteries around the world originated from initiations performed by and dharma transmitted by H.H. Great Dharma King Dodrupchen. Without H.H. Great Dharma King Dodrupchen, there would be no Longchen Nying-thik Great Perfection, which is the highest esoteric dharma in the world.
After reading the book A Treasury of True Buddha-Dharma in December of 2006, H.H. Great Dharma King Dodrupchen marveled at the accomplishments of H.H. Dorje Chang Buddha III Wan Ko Yeshe Norbu and promptly wrote a congratulatory letter. In the letter, he stated that the accomplishments of H.H. Dorje Chang Buddha III are truly miraculous and demonstrate in an extraordinary way the absolute truth of the Buddha-dharma.
