That's why I said Buddhism began as a philosophy and became a
religion.
Buddhism today (already centuries ago) is definitely mixed
with politics like other religions. If you read the history
of monastic involvement in politics, monks in Sri Lanka, Myanmar,
Thailand and Tibet were either direct participants or behind the
sence influencers.
In fact, Buddhism is both philosophy and religion, it also
never separate of politic either, as the wise put
it, samsara is bodhi. In this regards, the involvement
of politic is not improper. If you would to explore Zen master Bao
Zhi Gong, Yong Ming Yan Shou amongst others who were with the
rulers, they exercised the politic of loving-kindness.
Trantric master Zhang Jia was being strongly regarded as politic
monk, but was cremated with over 10000 relics.
