Fyodor Dostoievsky
The brothers Karamazov1880
Love all creation as a whole and in its elements, each leaf, each ray, the animals, the plants. By loving everything, you will understand the divine mystery in things. Having once understood it, you will know it always, every day, and you will end up loving the whole world with a universal love.
