Kyon chalti hai pawan
because of evoporation
Kyon jhoome hai gagan
because of earth’s revolution
Kyon machalta hai mann
because of excessive respiration
Na tum janno na hum
but i just gave all the answers
Kyon aati hai bahar
because of change in season
Kyon lut-ta hai qaraar
because of mental tension
Kyon hota hai pyaar
because of fatal attraction
Na tum janno na hum
like i said these’re all scientific phenomenon
Kyon gum hai har disha
because u have lost the sense of direction
Kyon hota hai nasha
because of drug addiction
:k:
man from where did you get it.. 
oii, i love that song
uss ka hashr karr diya !!
