Agree. True love requires sacrifice. The only form of love that does not is so called self-love. But then you may ask if we should not love ourselves? But I will ask you in return are you talking about your flesh? Or your soul? How do you love your soul? But if you want to love your flesh, material nature of things which is temporary per se, what is noble in that? There is not much divine. But the source of true love is divine.
