Yes, saving montly income ($1000/month as mno suggested) is one options for Ram Chandra Kafle, and I guess he can do that to treat his brother if the health problem his brother is going through is not the acute one and hence can be treated successfully after 4-5 years. But it is different, his brother's situation is very critical now and it seems that he is already hospitalized, may be already admitted to the ICU at Appolo Hospital in New Delhi. So, saving monthly income is not the option here and perhaps he can not get loan to treat his brother either from any where as it seems that he is an international students. 

I think we all can save his brother's life if we are bit more generous, we don't have to have a regular income or don't have to cut short our money/saving to support our family back home in order to contribute little, may be $10-15 or more. If we can raise some $12-15000, that is also a substantial or big support to cure his brother I guess.
