"The Greek term for repentance, metanoia, denotes a change of mind, a reorientation, a fundamental transformation of outlook, of man's vision of the world and of himself, and a new way of loving others and God. In the words of a second-century text, The Shepherd of Hermas, it implies "great understanding," or discernment."
Change starts at the simpliest of ways,or at least it can be attained in that fashion by many if they try."The Key is wanting to Try"
I represented this in class on day, in a simple way; I wrote my "g's" (in my hand writing fashion) in one way,so I decided I would just start writing my "g's" in another way,within a few days it was the "new way". simple yet effective,just takes being aware,any trying.
Metanoia (from the Greek μετάνοια, metanoia, "changing one's mind") has been used in psychology since at least the time of American thinker William James to describe a process of fundamental change in the human personality.
The term derives from the Ancient Greek words μετά (metá) (meaning "beyond" or "after") and νόος (noeō) (meaning "perception" or "understanding" or "mind"), and takes on different meanings in different contexts.
