Henosis ( Ancient Greek: ἕνωσις) is the classical Greek word for mystical "oneness", "union" or "unity." In Platonism, and especially Neoplatonism, the goal of henosis is union with what is fundamental in reality: the One ( Τὸ Ἕν), the Source, or Monad. [1] The Neoplatonic concept has precedents in the Greek mystery religions [2] as well as parallels in Eastern philosophy. [3] It is further developed in the Corpus Hermeticum, in Christian theology, soteriology and mysticism, and is an important factor in the historical development of monotheism during Late Antiquity.


The term is relatively common in classical texts, and has the meaning of "union" or "unity". [note 1]
