Henosis

Henosis () is the classical Greek word for mystical "oneness", "union" or "unity". In Neoplatonism, henosis refers to the unification with what is fundamental in reality: the One (Τὸ Ἕν), the Source, or Monad. The Neoplatonic concept has precedents in the Greek mystery religions as well as parallels in Eastern philosophy. It is further developed in the Corpus Hermeticum, in Christian theology, Islamic Mysticism, soteriology and mysticism. Henosis is also an important factor in the historical development of monotheism during Late Antiquity.

==Etymology== The term is relatively common in classical texts, and has the meaning of "union" or "unity".
