I have a spare copy of "Obedience is Life: Elder Ephraim of Katounakia," by Elder Joseph of Vatopaidi, published by the Monastery of Vatopaidi on Mt. Athos. Elder Ephraim (+1998) was a disciple of Elder Joseph the Hesychast and lived in the harshest desert region of the Holy Mountain. The cost is $20, which includes shipping within the United States. Email me for more information.
In Christ,
Christophoros
