Often, an epiphany begins with a small, everyday occurrence or experience. For example: In the middle of a typical argument with his wife, a man realizes he has been the one causing every single argument, and that in order to keep his marriage, he must stop being such an aggressive person.
epiphany means when one has a realization or discovery, and so I think that personal epiphany would be when one discovers or is revealed of something. An example would be "Eric had an epiphany of life" meaning he understood or realized something relating to life.
