Kahin to.. kahin to
Hogi wo,
Duniya jahan tu mere saath hai..


Jahan mein, jahan tu,
Aur jahan, bass tere mere jazbaat hai,
Hogi jahan subah teri,
Palko ki, kirano mein,
Lori jahan chand ki,
Sune teri baahoin mein..


Jaane naa kahan wo duniya hai,
Jaane naa wo hai bhi ya nahi,
Jahan meri zindagi mujhse,
Itni khafa nahi..
Jaane naa kahan wo duniya hai,
Jaane naa wo hai bhi ya nahi,
Jahan meri zindagi mujhse,
Itni khafa nahi..


Saasein kho gayi hai kiski aahon mein,
Mein kho gayi hu jaane kiski baahon mein,
Manzilon se raahein doodhti chali,
Kho gayi hai manzil kahin rahon mein..


Kahin to, kahin to,
Hai nasha..
Teri meri har mulaqaat mein,
Hoton se, hoton ko,
Chumti, o rehte hai hum har baat pe,
Kehti hai fiza jahan,
Teri zamin aasmaan..


Jahan hai tu, meri hassi,
Meri khushi, meri jaan...


Jaane naa kahan wo duniya hai,
Jaane naa wo hai bhi ya nahi,
Jahan meri zindagi mujhse,
Itni khafa nahi..
Jaane naa kahan wo duniya hai,
Jaane naa wo hai bhi ya nahi,
Jahan meri zindagi mujhse,
Itni khafa nahi..
Jaane naa kahan wo duniya hai,
Jaane naa wo hai bhi ya nahi,
Jahan meri zindagi mujhse,
Itni khafa nahi..
