The Hesychast is a collection of several short works collected together about the contemplative practice of Hesychasm, or divine quietness. This work is compiled from the writings of the 14th century Greco-Serbian monk, Gregory of Sinai, also known by his Slavic named Grigorije Sinaita. His life and works would go on to be influential in the Byzantine world for the next century, and remain a significant component in monastic contemplation in the Orthodox churches, as well as in the Byzantine Catholic and Italo-Albanian Catholic churches as well.
