The first half of this book is a recollection of life as a monk on Mt Athos (the second half is a collection of the monk's teachings as an elder): Wounded by Love: The Life and Wisdom of Saint Porphyrios.
Another good book is The Gurus, The Young Man, and Elder Paisios by Dionysios Farasiotis. This one has a lot more detail about life on Mt Athos. Also, it's important to note that Elder Paisios has been venerated and is now Saint Paisios.
