NA TUM JANO NA HUM...

kyon chalti hai pawan...
because of evaporation

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 bahaar...
because of change in season

kyon lutata hai karaar...
becuase of mental tension

kyon hota hai pyaar...
because of fatal attraction

na tum janno na hum...
like i said these are all science phenomena

kyon gum hai har disha...
because u have lost the sense of direction

kyon hota hai nasha...
because of drug addict
