There is a partially Hindi (there is only a couple of lines in Hindi; rest is in English) song titled as "9 Parts of Desire". Here is the YouTube link to that song.

The song has lyrics like,
Parde ke peeche (Behind the veil)
Burns a fire.
Parde ke peeche (Behind the veil)
9 parts of desire.
What does exactly this line mean? What is it referring to?
