Then I went there, full of curiosity, to St. Paisios and told him: "What did you talk about, Elder? What did you discuss?"
He told me with disarming simplicity: "Eh, the 'Lord Jesus Christ... [i.e. the Jesus Prayer]"
I expected them to discuss the 666, the 12 bishops, or various ecclesiastical topics. But they prayed together. They found an opportunity to pray together, to "breathe together" in prayer.
