When lust goes love appears; and out of love comes longing. In love there can never be satisfaction, for longing increases till it becomes an agony which ceases only in union. Nothing but union with the Beloved can satisfy the lover.
Now the lover continuously witnesses the glory of the Beloved’s will; and in the witnessing does not even think of union. He willingly surrenders his entire being to the Beloved, and has no thought of self left. This is the stage when love is illumined by surrender.
