क्यों चलती है पवन
because of evoporation

क्यों झूमॆ है गगन
because of earth's revolution

क्यों मचलता है मन्
because of excessive respiration

न तुम जानॊ न हम
but i just gave all the answers

क्यों आती है बहार
because of change in season

क्यों लुटता है करार्
becuase of mental tension

क्यों होता है प्यार
because of fatal attraction

न तुम जानॊ न हम
like i said these are all science phenomena

क्यों गुम् है हर् दिशा
because u have lost the sense of direction

क्यों होता है नशा
because of drug addiction.

Ok enough leave it now.
