Hermann Hesse said this quote

Oh, love isn't there to make us happy. I believe it exists to show us how much we can endure.

~ Hermann Hesse

It may be important to great thinkers to examine the world, to explain and despise it. But I think it is only important to love the world, not to despise it, not for us to hate each other, but to be able to regard the world and ourselves and all beings with love, admiration and respect.

~ Hermann Hesse

So she thoroughly taught him that one cannot take pleasure without giving pleasure, and that every gesture, every caress, every touch, every glance, every last bit of the body has its secret, which brings happiness to the person who knows how to wake it.

~ Hermann Hesse
