This is a collection of texts on prayer, taken from Greek and Russian sources. The spiritual teaching of the Orthodox Church appears here in its classic and traditional form, but expressed in unusually direct and vivid language. The Art of Prayer is concerned in particular with the most frequently used and best loved of all Orthodox prayers - the Jesus Prayer. It deals also with the general question 'What is Prayer?', with the different degrees of prayer from ordinary oral prayer to unceasing prayer of the heart, with the dangers of illusion and discouragement, and the need for seclusion and inner peace.

The Philokalia is an important collection of writings by Fathers of the Eastern Church dating from the fourth to the fourteenth century. It exists in three versions: the Greek, complied in the eighteenth century; the Slavonic; and the Russian.

The Russian text, translated by Bishop Theophan the Recluse in the nineteenth century, and consisting of five volumes (with which a sixth is sometimes associated), is the most complete of all three versions. It is the Russian text that has been used in translating into English this selection, which presents a range of Philokalia writings concerning the Jesus Prayer.
