In the writings of avva Isaiah of Scetis the hesychastic teaching and its terminology is an inseparable part of monastic practice. Together, they set up milestones of a single path of the monk's life.
As such, silence and solitude joint with ascetism are taught by spiritual fathers of the ascent (Climacus, Isaiah) as well as those of the Philokalia. Their teaching and terminology arrived from the monastic East to Europe where they were transformed in the particular ways of both western regular monasticism and lay spirituality.
