You are asking about the definition of reality and not about what reality is. The definition depends totally on the awareness or *realization* of the person who is defining the word 'reality' and that will variate with each individual.
Words, the same like symbols are standing for a more or less complex concept, that describes the meaning of this word. So a person can include this concept into ones knowledge base, even without having any experience, not even understanding the full meaning. The vague feeling of knowledge mostly is enough, that it is not enough, shows when there is a strong challenge in a real life situation...
Let me give you an example: The Eskimos have about 200 words for 'snow', we have only a few, but the Eskimos live all year in snow and their life depends on it. We have only very few words for *love* and only one word for *reality*. That tells something about our awareness, doesn't it?
As a 'normal' person living our daily happenings, we know only one reality and that is the *fake reality* established in our society. Now this gives a distinct meaning to the simple word 'reality', although the word 'fake' gives a negative meaning and so might be rejected from people for whom their reality is the only one they know or better said: the reality they live. There is no need for another reality, people don't want to know about something else that only will irritate them. They firmly will defend their state of being and that is their limitation to their established 'reality'.
If I give you my definition of *reality* then you can't understand it, because that wouldn't be the 'reality' you are living. You might include it into the intellectual collection of concepts you have gathered and you will identify with it and so it can give you an additional good feeling of security and importance, but that's all. And it is not especially good, because not even the most beautiful or complex concept can substitute ones limited reality with something, even though it is more sophisticated. That's the danger of modern 'spiritual concepts', these give a picture of a possible reality that then is integrated into ones self image, but it is not *realized*, that is: brought into ones *(fake)reality*.
Now you see that I used the word 'reality' several times and the meaning was always different.
Conclusion: Let's say the final *reality* is *white light*, before this state is reached, it can be experienced as many different colors, that are coming from the one *light*. This describes my *reality*.
I hope this gives you some light...
