Virginia Woolf is recognized as one of the great innovators of modern fiction. Her experiments with point of view have influenced many writers that follow her. But one particular interesting technique that does not seem to receive much attention is her use of moments of being.
.... To wonder why some moments are so powerful, and memorable - even if the events themselves are unimportant - that they can be vividly record while other events are easily forgotten. She concludes that there are two kinds of experiences: moments of being and (moments of) not being.
Virginia Woolf never explicitly defines what she means by moments of being. Instead, she provides examples of these moments and contrasts them with moments of what she calls not being.
Moments of not being appear to be moments that the individual is not consciously aware of even as she experiences them. She notes that people perform routines such as walking and shopping without thinking about her. This part of the life is "not live consciously" but instead, is embodied in "a kind of no descript cotton wool".
It is not the nature of the actions that separates moments of being from moments of not being.
One activity is not intrinsically more mundane or more extraordinary than the other. Instead, it is insensitive of feelings, one's consciousness of experience, that separates of the two moments.
A walk in the country can easily be hidden behind the cotton wool for one person, but for Woolf the experience is very vivid. Virginia Woolf asserted that the moment of being, this flashes of awareness, reveal a pattern hidden behind the cotton wool of daily life, and that we, "I mean all human being - are connected with this: that the all world is a work of art. That we are part of the work of art". But the individual artist is not important in this work. Instead, she says of all people, "we are the words; we are the music ; we are the thing itself". This foo Woolf a moment of being is a moment when an individual is full unconscious of his experience, a moment when he is not only aware of himself, but catches a glimpse of his connection to a larger part hidden behind the opaque surface of daily life. Unlike moments of non being, when the individual lives and acts without awareness, performing acts as if asleep, the moment of being opens up and hidden reality.
Moments of being can be found throughout Virginia's fictions: Mrs. Dalloway, To the lighthouse, Between the acts. Unlike Joyce's epiphany, this moments do not lead to decisive revelation for the characters. But they provide moments of energy and awareness.

That allow the character who experiences them to see life more clearly and more fluidly, if only briefly. And some characters try to share the vision that they glimpse, making in the work of art that is life visible to others.
Mrs. Dalloway presents the two characters who are most receptive to moments of being in all of Wool's fictions: Clarissa Dalloway and Septimus Warren Smith. Clarissa experiences a moment of being while in the middle of what appear to be trivial acts indicating that it is not the actions, but the awareness that sets a moment of being apart from other experiences.
Throughout the day Clarissa is particularly aware of this threads of connection between herself and her surroundings. V. Woolf's moments of being are marked by particularly vivid and powerful language. Because these are moments of exact feelings, the language used to convey them must naturally be precise and evocative: the form and content must be in perfect symmetry.
It is time in a novel long stretches of narrative can be clothed in mundane language: not every scene is of equal value or must carry on equal weight. But in her moments of being V. Woolf uses a language that approaches poetry.

Epiphany is referred a narrative technique in fiction made we by James Joyce according to which everyone as sudden flashes of perception and inside. Epiphany is the twentieth night that is the sixth of January when Christ was visited by the three wise men and his divinity was revealed to the world.
Epiphany derives from the Greek word epiphanein: it means to manifest. In pre-Christian time it was used to record appearance of Gods and goodies. Traditionally the word excepted this specific religion association, but in our century it has been secularize to refer to other, non-divine forms of revelation.

JOYCE SECULARY EPIPHANY
Joyce was interested in sudden, dramatic, starting moments which seemed to have heighten significance and to be surrounding with the coming of magical aura.
The first concept of epiphany was first outlined in Stephen Hero.
