There is only one reality. However- there are as many interpretations to it as there are people.

Why is it so, that man lives not in his inner world? And claims my inner world is different from yours, when there is only one reality. There can be fundamental and lasting views on reality when one sees the net futility of self-continuance. 

Man spends his life defending that what is not - which is the ego and identity that herald as blind consumption. They can be experienced- but they are that-that are not.

 It is because the scale at which a man pursues life- is low level. Every time there is a me, There is restlessness. The reality, holds no instances of me.  We are born and we believe we are the body- so we look for rescue from the restlessness through the body.

So, Am I the most important thing in the world? The answer to it lies in the scale. Yes, I am the most important thing in the universe, without me- the universe doesn't exists. When I come into existence - I sees the universe- when I disappear, the universe disappears.

So its very important that I is self-actualized and lives to the fullest because I is an expressing itself in the universe. That is why I exists. That's all I has got- that is the full experience of I. Not the blind consumption.
