The Ascetic Words of Saint Isaac of Syria are derived from his personal experiences and constitute the fruit of his living charismatic theology. Beyond the spiritual and theological authority that characterizes the work of Saint Isaac, the Syrian father seems to have a profound understanding of the psychology of the depths of the human soul.

This work, delving into the thoughts of Saint Isaac, brings to the contemporary era elements and data that reveal that the teaching of the sacred hesychast—recorded fifteen centuries ago—regarding psychosomatic illness and the quest for psychosomatic health can stand with reliability and authority alongside modern views in Psychiatry and Psychology.

In the ever-relevant work of the theology and anthropology of hesychasm, even psychologists and psychiatrists have recently begun to engage. The Ascetic Words of the hesychast father prove to present a coherent and fruitful perspective on the etiology and therapeutic approach to anxiety, melancholy, neuroses, profound sadness, and suicides.

The message of the words of the Holy hesychast is not directed only at hermits and recluses. It primarily addresses the secular, rulers, children, adults, and the elderly, the rich and the poor, scientists and the uneducated, people of every nationality and race, prisoners, the dependent, those suffering mentally and physically, to all the weary and also the indifferent.
