As Buddhism spreads to the rest of the world I feel the lamas/teachers have to find more ways to sharing the dharma with practitioners. In some cases blue jeans work better, than robes. People who are in robes can be a tad bit intimidating at times I must admit, when I recollected how I viewed the monks in their robes.
For Lama Osel not to manifest his buddha like activities, as Ensapa mentioned is due to broken samaya with Dorje Shugden. FPMT came up and expanded due to the Lama Yeshe and Dorje Shugden, huge pujas of dorje Shugden was done in the hey days of Kopan. Now once FPMT have grown huge Dorje Shugden is just discarded like a way side deity, and practitioners in FPMT conduct witchhunts to root out Dorje SHugden practitioners? It does not sound right which ever way you look at it. If the lamas of old do not find a problem with Dorje Shugden propitiation why do we find problems with it? Are Lamas in the past 300-400 years more deluded than the beings and lamas of these times? That can't be true as we are in the degenerate age, things are getting worst with time.
