The thing is, Vajratruth, we still need to live this life as a human being with 5 aggregates intact and very much in-need of a 'nationality' to live in a particular 'country' to enable us to practice the so-called dharma to obtain 'attainments' and 'realisations' for us to 'save all sentient beings from drowning in this sea of samsara'... the harsh truth here is we are still very much limited and restricted by the samsara's rules!
Look how HH Dalai Lama have to run away so that he can continue to serve Tibetans and sentient beings; and similarly look how much difficulties the Dorje Shugden practitioners have to go through just to uphold this holy Dharma Protector's practice for the sake of helping spreading Lama Tsongkhapa's teachings.
As such, in the same manner, if the Tibetans in China are not allowed to continue with their traditions and to practice their religion based on their pure lineage, there is no 'saving sentient beings' to talk about anymore. Nothing is left of the pure teachings of Buddha there, only left with commercialized 'Buddhism' to attract tourists to the authentic monasteries for worldly wealth. How much can you trust a political party run by a group of communists who do not have any belief in Buddha Dharma but is determining the spiritual leaders of Tibetans; like what we already witnessed in the many cases of identifying reincarnation of high lamas.
Do not comment with views looking at the crisis by standing in your own country but try to visualize yourself living in Tibet under Chinese's rule. What is your future? What will happen to your practice once you do not have your identity as Tibetan anymore? What will happen to your children, will they be taught Tibetan language so that they can study the Dharma texts? Are they allowed to learn pure Dharma without distortions?
