TWO SONGS THAT I HAVE BEEN THINKING ABOUT:

Humne dekhi hai in aankhon ki mehakti khushbu, Haath se chhooke ise rishton ka ilzaam na do.
Sirf ehsaas hai yeh, rooh se mehsoos karo, pyaar ko pyaar hi rehne do koi naam na do.

Sigh. What a lovely line, and how true.

And the second song, to my mind linked inextricably with the first:

Na Main Tumse Koi Ummeed Rakhoon Dilnawazi ki,
Na Tum Meri Taraf Dekho, Ghalat Andaaz Nazron Se.
Na mere dil ki dhadkan, ladkhadaaye, meri baaton mein,
Na Zaahir ho tumhaari kashmakash ka raaz nazron se.
