Henosis

Henosis (Ancient Greek: ) is the word for mystical "oneness", "union", or "unity" in classical Greek.

In Platonism, and especially Neoplatonism, the goal of henosis is union with what is fundamental in reality: the One (), 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, 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".

To get closest to the Monad, One, each individual must engage in divine work (theurgy) according to Iamblichus of Chalcis. This divine work can be defined as each individual dedicating their lives to making the created world and mankind's relationship to it, and one another, better. This is done by living a virtuous life seeking after one's Magnum opus. Under the teachings of Iamblichus (see the Egyptian Mysteries), one goes through a series of theurgy or rituals that unites the initiate to the Monad. These rituals mimic the ordering of the chaos of the Universe into the material world or cosmos. They also mimic the actions of the demiurge as the creator of the material world.
