Through this video, we witnessed that these High Lamas are indeed very powerful in their spiritual practice. Most of them have reincarnated, e.g: H.H Zong Rinpoche, H.H Trijang Rinpoche.
If practicing Dorje Shugden is really bad, how can these High Lama reincarnate as human forms again and continue benefiting others sentient being, not to mentioned, they continue to be the lineage holder on this life. This is no logic on the accusation of practicing Dorje Shugden is evil. If practicing Dorje Shugden is evil, by law of karma, is impossible to reincarnate as human forms not to say continue on spreading the Buddhism in this life time.
