Uncreated but alive, the word of Abba Isaac is mentioned briefly and accurately in the distortions of the struggling faithful on their way to deification. It is not subjected to an externally preconceived intellectual plan, but moves freely and naturally in the supernatural realm. Thus, virtues and mental states are unfolded mixed and scattered, but at the same time they are harmonized and balanced as a whole. Basic issues of spiritual life are addressed, such as the war of the devil, temptations, fasting, patience, cultivation of the soul, purity of the heart, means of salvation, etc.
