"It is widely known that Fr. Porphyrios saw the organs and their function within the human body. He had told me that when he first began to see the internal organs, he did not know what they were that he was seeing. So he went to the Eleftheroudakis bookstore and bought an atlas of anatomy and a thousand-page book of human physiology, written in impeccable cleanness, and studied them, in order to acquire the necessary theoretical foundation.  What I still remember with awe, however, is the palpation of the pulse that he did when he wanted to diagnose mental illnesses. He did it to me and to many others, and when I asked him once, he answered me:

Medicine is not only knowledge; it is also a mystery, which you doctors do not know! (Catholic Elias Kouroumalis, in "The Landmark of Holiness in the Modern World")"
