I understand the outcry by fellow posters against the OP's post. The way it is written (by somebody else) and posted (by OP) do sound a little out of line.
But, I have heard this thing before. Muna Madan, I believe, was based upon some old Nepal bhasa song about a guy going overseas for labor. The text quoted in the original post sound like the exact line from that song. Now, did Laxmi Prasad translated the whole Nepal Bhasa song? I don't know.
There was a discussion about similar thing in Sajha a while back. I think Rahulvai might have some insight on this; I am not sure if it was regarding Muna Madan or some other epic by the Mahakavi. This accusation is not entirely baseless.
