If we only see Ugyen Trinley Dorje’s situation from one angle, yes it may sound ungrateful. But why he makes such decision? A lot of people may see he move away from India but the truth is he makes a brave move from the Tibetan leadership. Ugyen Trinley Dorje express himself before that :
1 )he has no freedom of speech within the Tibetan settlements. He was forced to be involved in politics, something he was ill-prepared to deal with.
2) Ogyen Trinley said that historically, the Karmapas are purely spiritual leaders who are not politically involved. And even in this.
3) So not only did he fail to receive a complete spiritual education, but he was also not given the tools to succeed in a secular environment.
The CTA has a trend of splitting lineages and keeping them divided. The CTA intentionally interfered in the Karma Kagyu’s religious affairs and after splitting the lineage, did not lift a single finger to mend the rift or even mediate between both parties. They created the issue in the first place, dividing large groups of people in order to weaken and conquer them. Likewise, the CTA instigated the unjust and illegal ban against Dorje Shugden practitioners, splitting the Gelug lineage in half as well. It is clear the CTA does not care about spiritual practice or its preservation; the only thing that matters is political dominance over the Tibetan people and they have achieved this by attacking what is at the very heart of Tibetan culture – its religion.
