Hesychasm

Hesychasm (/ˈhɛsɪkæzəm, ˈhɛzɪ-/)[1] is a mystical tradition of contemplative prayer in the Eastern Orthodox Church. Based on Jesus's injunction in the Gospel of Matthew that "whenever you pray, go into your room and shut the door and pray to your Father who is in secret; and your Father who sees in secret will reward you",[2] hesychasm in tradition has been the process of retiring inward by ceasing to register the senses, in order to achieve an experiential knowledge of God (see Theoria).
