Unshaped but alive, the words of Abba Isaac briefly and accurately refer to the alterations of the struggling believer during their journey towards deification. They are not subjected to an externally preconceived intellectual plan, but move freely and naturally in the supernatural realm. Thus, virtues and mental states unfold mixed and scattered, yet harmonized and balanced as a whole. Fundamental issues of spiritual life are addressed, such as the war of the devil, temptations, fasting, patience, cultivation of the soul, purity of heart, means of salvation, and more.
