Aaj kal jindagi mujhase hai keh rahi
Tu jo meri maane toh chal
Deewaane sapano ki raahon mein tu
Saari khushbuo saari roshani
Ko le le inn baahon mein tu
Abb hai tu jahaan,
Din raat saare naye hain
Aaraju jawaan jajbaat saare naye hai
Naye raaste hai tere waaste
Panaaho mein tu
O ho tere liye nayi hai
Jamin naya aasmaan
Likh de hawaao pe koyi nayi daastaan
Tere liye nayi hai jamin naya aasmaan
Likh de hawaao pe koyi nayi daastaan


Jindagi ne dastak di toh
Dil ki sab khidkiyaan
Khul gayi haan khul gayi
Honto pe jo jamin thi
Woh saari khaamoshiyaan ghul gayi
Haan ghul gayi
Kitane lamahon ne mujhako
Jaise hai hairaan kiya
Kitani baaton ne
Dil ko aake hai chhu liya
Chaahatein kayi hai
Dil mein abb jagmagaayi
Raahate kayi hai
Mujhe kehane ko aayi
Pehchaane saari muskaane
Saari bhar le migaahon mein tu
O ho tere liye nayi hai
Jamin naya aasmaan
Likh de hawaao pe koyi nayi daastaan
Tere liye nayi hai jamin naya aasmaan
Likh de hawaao pe koyi nayi daastaan.
