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
