Four Hundred Texts on Love
Κεφάλαια περὶ ἀγάπης
Ἀγάπη ἐστὶ διάθεσις ψυχῆς ἀγαθή, καθ' ἣν οὐδὲν τῶν ὄντων τοῦ Θεοῦ γνώσεως προτιμᾶται.
Our renderingLove is a good disposition of the soul in which nothing that exists is preferred to the knowledge of God.
What it is
Maximos the Confessor (c. 580–662), the greatest Byzantine theologian before Gregory Palamas, composed four centuries — four sets of one hundred chapters — on love of God and neighbor as the summit of the Christian life and the royal road to theosis. The terse, aphoristic form was designed for memorization and meditation, and the chapters distil patristic wisdom — Evagrius, Gregory of Nyssa, Dionysios the Areopagite — into an integrated account of the ascetic and contemplative life. They form a substantial portion of Philokalia vol. 2 and were universally read in Byzantine monasteries; scholars have described them as among the most comprehensive treatments of deification in the Philokalic corpus. The text circulated at every Orthodox court touched by the Philokalic tradition.
Why it still matters
The Four Hundred Texts reward daily reading at the rate of one or two chapters; their insistence that love of God and love of neighbor are inseparable makes them equally applicable to active and contemplative Christians and a natural companion to the Sermon on the Mount.

On Watchfulness and Holiness (Pros Theodoulos)
Πρὸς Θεόδουλον, περὶ νήψεως καὶ ἀρετῆς
Hesychios of Sinai, abbot of the monastery on Mount Sinai (date uncertain, probably 8th–9th century; not cited in sources until the 13th century), addressed this extended treatise on watchfulness to a disciple named Theodoulos, arranged in two centuries of short chapters. It teaches that watchfulness is a method of 'continual fixing and halting of thought at the entrance to the heart,' providing the fundamental technique of hesychast mental prayer in its most distilled and teachable form. Nikodemos the Hagiorite initially identified the author with the 5th-century Hesychios of Jerusalem, but modern scholarship treats them as distinct persons of different centuries. The text appears in Philokalia volume one and reached its widest circulation through the Philokalic revival, which carried it into all the court and monastic networks touched by that collection.
One Hundred Chapters on Spiritual Knowledge
Κεφάλαια ἑκατὸν περὶ τελειότητος πνευματικῆς
Diadochos of Photike (c. 400–486), bishop of a town in Epirus who participated in the Council of Chalcedon in 451, wrote one hundred compact chapters on spiritual perfection that scholars consider among the earliest sustained theological treatments of invoking the divine name in prayer as a complete spiritual method. His synthesis of continuous name-invocation with an integrated theory of spiritual attention and sobriety (nepsis) influenced Maximos the Confessor, John Climacus, Symeon the New Theologian, and ultimately the entire hesychast tradition. The text occupies a central place in Philokalia volume one, and its warmth of tone and clarity of argument have made it consistently the most recommended starting point within the collection for readers new to the Jesus Prayer.
Praktikos and Chapters on Prayer
Πρακτικός; Περὶ προσευχῆς
Evagrius Ponticus (345–399), a student of Gregory of Nazianzus at Constantinople who withdrew to the Egyptian desert, composed the Praktikos — one hundred chapters on overcoming the eight logismoi (destructive thoughts) — and the Chapters on Prayer, 153 chapters that constitute the first systematic theological account of pure or imageless prayer. Together they form the psychological and theoretical foundation on which all subsequent hesychast writing was built. Evagrius's speculative theology (including the pre-existence of souls) was condemned at the Fifth Ecumenical Council in 553, so the Chapters on Prayer circulated throughout the Byzantine period under the name of Nilus of Ancyra; modern scholars have reattributed them to Evagrius, but medieval and early modern court readers knew them only under the pseudonym. The Praktikos appears under Evagrius's own name in the Philokalia.
