The Philokalia (Ancient Greek: φιλοκαλία - love of the beautiful) is a collection of texts written between the 4th and 15th centuries by spiritual masters of the Orthodox Christian mystical hesychast tradition. They were originally written for the guidance of monks in the practice of the contemplative life. The book is the principal spiritual text for all the Orthodox churches and has exercised an influence far greater than that of any book other than the Bible in the recent history of the Orthodox Church. Alternates Monday-Saturday with the channel 'Daily Catechism of the Orthodox Church'.
