Saint Maximos Kavsokalyvites on Noetic Prayer.

A native of Lampsacus on the Hellespont,
Saint Maximos became a monk at the age of seventeen. When his spiritual
father died, he went on pilgrimage to Constantinople, where he took up
the ascesis of folly for Christ, pretending madness in order to conceal
his virtues and struggles from the world. He then went to the Great
Lavra of St Athanasius on Mount Athos, where he lived as a simple monk
in complete obedience.
One day, he was told in a dream to go to the summit of Athos to receive (like Moses) the tablets of the spiritual law. He prayed continuously atop the Holy Mountain for three days, after which the Mother of God appeared to him surrounded by angels. She gave him a miraculous loaf for his sustenance and told him to live in solitude on the wild slopes of Mount Athos. Henceforth he lived apart, barefoot in all weather.
He would build himself crude shelters of branches and brush; after living in one for a short time he would burn it and move to a new place. Thus he received the name Kavsokalyvites "the Hut Burner" from the other monks, who dismissed him as a madman.
