In the Qawwali the nature of love, lover, and beloved is expressed. In this the poetry of the Sufi excels the love poems known to the world, for in it is revealed the secret of love, lover and beloved, the three in one. Apart from the philosophy of the whole being, one can see the delicacy and complexity of their poems, rich with conventions and adorned with metaphor. Hafiz, Rumi, Jami, and many others among the Sufi poets, have expressed the secret of the inner and outer being in the terminology of love.
