Father Zossima in The Brothers Karamazov: “By the experience of active love, try to love your neighbours actively and tirelessly. The more you succeed in loving, the more you’ll be convinced of the existence of God and the immortality of your soul. And if you reach complete selflessness in the love of your neighbour, then undoubtedly you will believe, and no doubt will even be able to enter your soul. This has been tested. It is certain.”

F. Dostoevsky
