Sarai

“I think I could stand anything, any suffering, only to be able to say and to repeat to myself every moment, 'I exist.' In thousands of agonies -- I exist. I'm tormented on the rack -- but I exist! Though I sit alone in a pillar -- I exist! I see the sun, and if I don't see the sun, I know it's there. And there's a whole life in that, in knowing that the sun is there.”
― Fyodor Dostoyevsky, The Brothers Karamazov
