Three lectures; two by Anglican (philosopher, cleric), one by monk of Mt. Athos (Eastern Catholic). Excellent information
regarding both angels of light and demons. Monk provides information of early desert fathers and benefit of their knowledge.
Early hermits went to desert, combated demons on behalf of the Christian world as well as for their spiritual progression. Hermits
often besieged due to their having left the temporal world, but praying for that world infuriates the demons. Information on modes in which the demons enter the interior of the soul, as well as differences between body, soul and spirit realms.
