Tribute from Professor Jeffrey Hopkins....
Given the variety and complexity of the Tibetan teachings and the present crucial point in their history, it is important that we realize how much responsibility for the continued availability of this teaching even one person can assume. It is clear that Lama Yeshe did not wait for others to work at incorporating the doctrine; it is clear that he did not view the dharma as a spectator sport, watching someone else and then second-guessing. Instead, it is clear that he decided that he would do what he could do. He showed what a difference a single person with sincere motivation can make. Even those who, like myself, were not formal students of Lama Yeshe, still have much to learn from his activities of compassionate energy."
