The Philokalia is the most influential book in the recent history of the Orthodox Church, aside from the Bible. It is an anthology of thirty-six spiritual texts written between the fourth and fifteenth centuries by the masters of Eastern Orthodox Christianity, tracing a continuous tradition of the prayer of the heart, or hesychasm, in which the Jesus Prayer plays a growing role, from Evagrios of Pontos to Gregory Palamas. First published in Greek in 1782, and revered for offering a rich tapestry of wisdom on the path to union with God, the texts, largely of monastic origin, serve as a guide to lay people as well as monks in their pursuit of contemplative prayer, 'inner asceticism', and the purification of the soul.
