Elder Porphyrios said the following about his meeting with Elder Paisios:
"One day on Mount Athos I was traveling by tractor. Paisios was there. The two of us would say the Prayer mystically. Our souls were united. At one point he got off but we continued. Well, you should have seen then! Even though he was leaving he rushed towards me and hugged me noetically. You should have seen the unity of souls. You are able to love others spiritually, to hug them, to feel them, even from a distance."
