Kisi Ka Khwaab

Bahut dur ka safar taiy karke aaya hu
Apne jazbaat ko qaid kar k aaya hu
Zindgi me paane ki khwahish to kuch aur thi
Par shayad kisi ka khwaab pura karne aaya hu

Bahut dur nikal aaya hu ki ab wapas ja nahi sakta
Mai kisi ki aas ko yun bhula nahi sakta
Zindgi k safar ka maza hi kuch aisa tha
Ki ab mai bhul kar bhi usko bhula nahi sakta
