Tagore’s works are mostly in Bengali, and often works of fiction. That makes it hard to distil his views on various issues.

I found this essay in English on Tagoreweb, which contains all his writings. In this Tagore questions the idea of nation, and insists that moral principles and humanity are greater. (This writing sounds like a talk although no reference about its date of publication or purpose is cited on Tagoreweb.)
