The third part of the book, “Birds of Heaven or the Journeys of the Soul in the Embrace of God,” talks about an in-depth search for monastic dispassion, so necessary in spiritual life, about efforts to understand the essence of this high state of spirit in comparison with the ascetic experience of the monks of Athos, Sinai and Egypt. The fourth part of the book introduces us to the deeply hidden and mysterious life of Athos monasticism, called hesychasm or sacred silence. The chapters of this book tell about the comprehension of the Divine dignity of every person, about the practice of sacred contemplation, which opens up the opportunity for the human spirit to believe in its own deification and acquire it in the fullness of its likeness to God.
