When lust is transformed and you enter into the city of love, you enter unattached. Remember, that is their definition of love. If love has attachment in it, it is lust, If love has no attachment in it, only then is it not lust. When you are in lust you are not really thinking of the other, thinking of your beloved or lover. You are simply using the other for your own ends. And of course, attachment is bound to be there, because you would like to possess him, and you would like to possess him or her forever. Because tomorrow also you may need, the day after tomorrow also you may need. You need a lover and you want to possess him.
