The thing is people don’t know about the word called “METAPHOR”.

The lyrics goes like this:

Oye hawan kund, maston ka jhund
Oye hawan kund, maston ka jhund

Oye hawan kund, maston ka jhund
Sunsaan raat
Ab aisi raat
Rakh dil pe haath
Hum saath saath
Bolo kya karenge…
Havan karenge, havan karenge, havan karenge
Havan karenge, havan karenge, havan karenge

It typically describes hostel life of bachelors. The first line “Oye Hawan kund, maston ka Jhund” describe the situation of bachelors when they are doing nothing, just like the “Hawan Kund” when there is no ritual is going on. It is just a pot, empty.

Next lines, “Sunsaan raat, ab aisi raat, rakh dil pe haath, hum saath saath bolo kya karenge, Havan karenge, havan karenge.:

This means that on a silent night, what we will do all together. The answer is that we will do something. Something to keep the fun going on. This is how the life of bachelors is. Or in the song’s context, the life of soldiers.

There is a small stanza come later in song:

O junglee aag si…
Bhadakti hogi…
Oye jungli aag si bhadakti hogi
Oye lakdi dil ki bhi sulagti hogi
Oye jungli aag si bhadakti hogi
Lakdi dil ki bhi sulagti hogi

I guess now you will understand what the song is all about. Prasoon Joshi is a well known writer of the country. He has written like 1000 songs. He has command over the language.

I guess I answered the question.
