Few months ago i read that Indian priest was booted out of pashupathinath temple in Nepal.
Now this was a shocking revelation to me that our most revered deity has been under the guardianship of a foreigner for a long time! An outsider accumulates all the wealth offered in cash and valuable kind and sends it off to his country. This must be unacceptable to everybody – religious or atheist, Hindu or non-Hindu.
This is one example of Vedic Hinduism influence in Nepal that has hinder our nation towards progress.
I understand that dalits, sudras who are so called untouchable are not allowed to enter the Hindu temples in vedic Hinduism.
Now that will not happen if we practice Kirat Hinduism.

Therefore we should be glad that Indian priest are booted out of our sacred temples. This is one good thing done by our present government.
Hence if Nepal is to follow Kirat Hinduism, it will bring back the glory of the caste less Nepal again.
It has been proven by the scholars that during the rule of 7th Kirat King Jitedasti, Lord Gautam Buddha had visited the valley with his several disciples. Under Jitedashi rule, Buddhism flourished though Kirats practiced Saivite Hinduism and Mundhum.

Therefore Nepal will only continue to be Hindu Nation if other religions are also embraced.
Homeyji hence this will answer to your call that Nepal will continue to exist as Hindu nation.
