Metanoia

Metanoia (from the Greek, metanoia, changing one's mind) in the context of theological discussion, where it is used often, is usually interpreted to mean repentance. However, some people argue that the word should be interpreted more literally to denote changing one's mind, in the sense of embracing thoughts beyond its present limitations or thought patterns (an interpretation which is compatible with the denotative meaning of repentance but replaces its negative connotation with a positive one, focusing on the superior state being approached rather than the inferior prior state being departed from).

Biblical references
From the Greek —compounded from the preposition (after, with) and the verb  (to perceive, to think, the result of perceiving or observing)—metanoia means "a change of mind". In Christianity, the term refers to spiritual conversion. The word appears often in the Gospels. It is usually translated into English as "repent":


 * and saying, "The time is fulfilled, and the kingdom of God has come near; repent, and believe in the good news."
 * (Mark )
 * (Mark )

Theology
In theology, metanoia is used to refer to the change of mind which is brought about in repentance. Repentance is necessary and valuable because it brings about change of mind or metanoia. This change of mind will result in the altered persona deprecating sin, though replicating good will, benevolence, and integration of self in relation to Universal harmony or deity. The two terms (repentance and metanoia) are often used interchangeably.

However, the prefix "meta-" carries with it other variants that are consistent with the Eastern Greek philosophical mindset, and perhaps is at odds with Western views. "Meta-" is additionally used to imply "beyond" and "outside of." E.g., metamorphosis as a beyond-change; and, metaphysics as outside the limits of physics. "Meta" also means "next to"or "after" as in metaphysics, where the books we call metaphysics were placed next to or after the books on physics.

The Greek term for repentance, metanoia, denotes a change of mind, a reorientation, a fundamental transformation of outlook, of an individual's vision of the world and of her/himself, and a new way of loving others and the Universe. In the words of a second-century text, The Shepherd of Hermas, it implies "great understanding," discernment. It involves, that is, not mere regret of past evil but a recognition by a person of a darkened vision of her/his own condition, in which sin, by separating her/him from Deity, has reduced her/him to a divided, autonomous existence, depriving her/him of both her/his natural glory and freedom. "Repentance," says Basil the Great, "is salvation, but lack of understanding is the death of repentance." Repentance thereby acquires a different dimension to mere dwelling on human sinfulness, and becomes the realization of human insufficiency and limitation. Repentance then should not be accompanied by a paroxysm of guilt but by an awareness of one's estrangement from Deity and one's neighbor.
