I never saw a christians burial ground in Pashupatinath area. Below is the news which was in BBC. 

The Himalayan country of Nepal is predominantly Hindu, but over the past few decades Christianity has grown in popularity - especially amongst poor and tribal Nepalis, attracted by the opportunity to escape the rigid caste system.

As the religion grows, the question of where to locate graveyards is causing friction between Christian communities and the government.

Until recently, Christians in Nepal's capital Kathmandu could bury their dead in the grounds of the Hindu Pashupatinath Temple. But the temple authorities now say there is no space for more bodies. Take a look with Dr Sundar Thapa, chairman of the New Constitution for the Christian Community in Nepal.

jaye hosh BBC ko and jaye hosh christians brother and sisters haruko. 

Not sure if it's a Christian one, but there is definitely a cemetery in the Pashupatinath. And I think the caste system comes with the culture more than the religion really. It's a dying tradition, but being from Kathmandu, I don't think I can speak for the rest of Nepal.

 I think more than the attractiveness to leave the caste system in Hinduism,  a major incentive for especially these poor people is the generous packages the missionaries offer for converts. I remember going to Tatopani (?) for Bungee Jumping and there was a huge Christmas party celebrated mostly by locals who looked like recent converts. 

I don't know where I stand with regards to such activities with respect to whether the government should impose a stricter law on conversions. At least after conversion, these people are taken care of by these churches, otherwise they really had no one to take care of them, and everyone was set on exploiting them.
