here is the translation dear...
mushkil hai waqt vichore ka
its difficult time of separation
bina mahi guzara kaun kare
who can live without a soul mate
ek din hove te o lung jaawe
if its the matter of one day it can pass
saari umar guzara kaun kare
but who can live alone for the whole life
ghar aaja we mahi we ghar aaja
please come back home please come back...
in the song mahi is referred to a soul mate!
