Penitence, dispassion, and the mysticism of "pure prayer" are discussed in the third. Austerities are addressed in the fourth section, particularly fasting, prostrations, and prolonged standing. Ascetical perspectives on sleep, dreams, and the hypnogogic state are analyzed in the fifth. The depressive syndrome of acedia is discussed in the sixth. Evagrius's reports of auditory, olfactory, and visual hallucinations are analyzed in the seventh. Multiple complementary interpretations of demonic phenoniena are developed in the eighth section. Evagrius's psychotherapy for anger is reviewed in the ninth. Interpersonal relations among ascetics are considered in the tenth section. The study concludes with a summary.
