The Spiritual Tradition in Eastern Christianity is a comprehensive survey of the means, goals, and motivations of the ascetic life as represented in texts spanning the fourth and the nineteenth century. Contemporary examples are also included. The main themes are the dynamics of the soul, the disabling effects of the passions, mental and physical asceticism, the desirable condition of dispassion, and the experience of deification. A variety of topics are addressed, including hesychast prayer, religious weeping, the spiritual senses, dream interpretation, luminous visions, the holy 'fool', ascetic demonology, and pain in ascetic practice. Typical ascetic and mystical experiences are interpreted from the psychological and the neuroscientific perspective. Comparative analyses based on Sufism, Vedantic mysticism, and especially early Buddhist psychology highlight distinctive features of the Christian ascetic life. Major figures such as Evagrius Ponticus, Maximos the Confessor, Isaac the Syrian, and Symeon the New Theologian receive extensive individual consideration.
