Tumhare Bina

Hamein Tumse Pyaar Kitna Yeh Hum Nahin Jaante
Magar Jee Nahin Sakte Tumhare Bina

Suna Gham Judaai Ka Uthate Hain Log
Jaane Zindagi Kaise Bitate Hain Log
Din Bhi Yahan To Lage Baras Ke Samaan
Hamein Intezaar Kitna Yeh Hum Nahin Jaante
Magar Jee Nahin Sakte Tumhare Bina

Tumhe Koi Aur Dekhe To Jalta Hai Dil
Badi Mushkilon Se Phir Sambhalta Hai Dil
Kya Kya Jatan Karte Hain Tumhe Kya Pata
Yeh Dil Beqaraar Kitna Yeh Hum Nahin Jaante
Magar Jee Nahin Sakte Tumhare Bina

This is what I had written in the first letter (with some more lines of my own).

I love this song... it keeps playing in my head these days (and its been that way for quite a few weeks now).
