More on prayer for the departed

Young man, be not forgetful of prayer. Every time you pray, if your prayer is sincere, there will be new feeling and new meaning in it, which will give you fresh courage, and you will understand that prayer is an education. Remember, too, every day, and whenever you can, repeat to yourself, "Lord, have mercy on all who appear before Thee to-day." For every hour and every moment thousands of men leave life on this earth, and their souls appear before God. And how many of them depart in solitude, unknown, sad, dejected that no one mourns for them or even knows whether they have lived or not! And behold, from the other end of the earth perhaps, your prayer for their rest will rise up to God though you knew them not nor they you. How touching it must be to a soul standing in dread before the Lord to feel at that instant that, for him too, there is one to pray, that there is a fellow creature left on earth to love him too! And God will look on you both more graciously, for if you have had so much pity on him, how much will He have pity Who is infinitely more loving and merciful than you! And He will forgive him for your sake.

Fyodor Dostoyevsky, "The Brothers Karamazov"
