Vision of the Satan in Immense Light

St Isaac the Syrian. "The Ascetical Homilies".

A person called Malpa, who came from Edessa, was the author of the heresy of Euchites but he was a great ascetic and went through the harshest ascetical practices. It is said that in time of being a disciple of Julian the Blessed, also called Sava, he visited with him for a short time Mt Sinai and Egypt and there heard mysterious homilies of St Anthony about the purity and salvation of the soul. St Anthony was explaining that the mind made pure can contemplate the mysteries of the Holy Spirit and the soul by God’s grace can become passionless if only keeps the commandments and returns to its primitive healthy nature of Eden.

Knowing that the Elder Saw All the Sins of a Person, the Girl Concealed her Sin Anyway

Protopriest Vladimir Vorobyev. "Hieromonk Pavel Troitsky".

Story of Hegumenia Iuliania, when she was a young girl and wrote letters to elder Paul (Troitsky)

It was as long as several years before I felt enough courage to confess a special sin. I suffered a lot because of that but could not do anything about it. I feared to write to Fr Pavel about that, just putting at the end of every my letter to him the words of asking forgiveness and prayers. I believe it was for his prayers only the Lord gave me enough courage and I could confess my sin.
