ek muamma hai
ek muamma hai
samjhne ka na samjhane ka
ek muamma hai samjhne ka na samjhane ka
jindagi kahe ko hai
jindagi kahe ko hai
khwab hai diwane ka
ek muamma hai samjhne ka na samjhane ka
aur suniye mohtarma farmate hai
husn hai jaat meri
ishq sifat hai meri
husn hai jaat meri
ishq sifat hai meri

hu to mai
hu to mai
shama magar besh hai parvane ka
hu to mai
shama magar besh hai parvane ka
