The Philokalia

by Nicodemus of the Holy Mountain

Abba Philimon also said this: 'Thoughts about vain things are sicknesses of an idle and sluggish soul. We must, then, as Scripture enjoins, guard our intellect diligently (cf. Prov. 4:23), chanting undistractedly and with understanding, and praying with a pure intellect. God wants us to show our zeal for Him first by our outward asceticism, and then by our love and unceasing prayer; and He provides the path of salvation. The only path leading to heaven is that of complete stillness, the avoidance of all evil, the acquisition of blessings, perfect love towards God and communion with Him in holiness and righteousness. If a man has attained these things he will soon ascend to the divine realm. Yet the person who aspires to this realm must first mortify his earthly aspects (cf. Col. 3:5). For when our soul rejoices in the contemplation of true goodness, it does not return to any of the passions energized by sensual or bodily pleasure; on the contrary, it turns away from all such pleasure and receives the manifestation of God With a pure and undefiled mind.
