The rain falls because

Maine us se poochha kya dhoop mein barish hoti hai,
Yeh sun kar wo hansne lagi,
Aur hanste hanste rone lagi,
Phir dhoop mein barish hone lagi.

Ab ke sawan mein paani barsa bohat,
Paani ki har boond mein wo aaye yaad bohat.
Is suhaane mausam mein saath nahi tha koi,
Baadlon ke saath in aankhon se paani baha bohat.

It must have been a rainy day when you were born,
But it wasn't really rain,
The sky was crying because it lost his most beautifull angel...
Happy Rainy Day . . . :->
