INDIVIDUALITY

As we already know. I guess most of us??!! that we share a different perception or view of reality which we form out of our past experiences. Examples

1. Some people may like to eat vegetarian while others may prefer non veg.

2. Some people like to use ponds soap while other uses pears soap.

3. Some people enjoy public speaking while others gets their pulse rate speedup by just even thinking about speaking in public.

So the real concept to understand is we from our past experiences and likes and dislikes somehow make certain decisions consciously or unconsciously about life. and hence we live by those rules. 

So that we as a human being could live with peace and protection. 

HENCE RULE ONE-

We all have our personal point of view or perception or a window from which we filter reality. And obviously I am not saying this for the sake of a metaphor. Scientific research has shown it. 

That's why we are able to see, hear, feel stuff in our dreams even though our eye are shut while we are sleeping.

TRY THIS-

IF you are interested try this experiment. which I think is a classic examples of two different world within two different people. All you have to do is to tell your friend or brother or sister to recognize the song that you will play. But the rule is you have to play that song by tapping on the table. :)

What usually happens that the song taps might make perfect sense to you as u play but that same song happen to sound like a random tap for listener person. 

And as you will reveal what u were playing, then and there u will see him/her making perfect sense out of it.

OR YOU CAN SAY AFTER REVEALING HE/SHE IS ABLE TO MATCH.

METAPHOR-

Have you ever thought that how can someone believe some shi##tttt thought. I think you should hang on before thinking it as that shit thought might make totally perfect sense in his own reality.
