Recently H.H Dalai Lama says many things that is contradicting what he said previously. We all know that H.H Dalai Lama is the emanation of Chenrezig. First of all, an enlightened being like Dalai Lama, who is also an emanation of Chenrezig, whose life shouldn't be affected by any negative forces, if Dorje Shugden was one like what Dalai Lama had claimed. Secondly, there are many high Lama who practice Dorje Shugden has lived long, and some even reincarnated. For example 101st and 102nd Gaden Tripa who have lived long and practice Dorje Shugden. H.H Kyabje Trijang Rinpoche and H.H Kaybje Zong Rinpoche are the high Lamas that practice Dorje Shugden and have proven reincarnation. In Buddhism, one's long life or not, depends on their karma, why blame on the practice?
Thus, since this statement "Practicing Dorje Shugden will shorten Dalai Lama's life" came out from Dalai Lama's mouth, we should ask His Holiness back "Why practicing Dorje Shugden will shorten his life since there are so many high Lama already practicing it and live a long life?"
Anyway, personally, I find that recently Dalai Lama says many things that's contradicting. He also claimed that he never said cannot practice Dorje Shugden before, he never wanted Tibet independent, he even claimed that he never ban Dorje Shugden practice before. So, which one is true? Anyway, he's not my Guru. I don't have to listen to all he says, but I still respect H.H Dalai Lama, it is because I believe whatever Dalai Lama says or said, there must be something behind. He is Chenrezig, I believe all these are his divine play.
