If you did not understand, read it again. This is such an accurate and true sentence.
We are all prisoners of our illusions, how?
Well, look around, the things are just happening around you and things you just watch won’t affect you but the things you have attached to emotionally will affect your mood, and if those same things are totally irrelevant to someone else. That person just watches them, without emotions, but they are very important and emotional for you.
You see, it’s all in the way how you look at things.
This means that we all make ourselves a prison (cell) from our emotions and thus do not allow ourselves to grow and develop. Why?
Because we allow our emotions to limit us.
For the most part of your life, in most cases you just need to observe things and not react, it doesn’t require reaction or response for everything you see. In most cases you just need to observe them, it’s one of the best ways to control your emotions.
Remember, does not require everything that happens in this world your reaction.
Don’t let someone else’s behavior to destroy your inner peace.
Some things just happen and we humans like to attach importance to everything and in most cases misinterpret it. For example, People use the phrase “sunrise”, the sun does not rise and does not set, we (the earth) are turning and because of that the sun seems to rise, but we like to give everything the connotation that we are essential. That we are the most important but believe me we did not.
Look at these two pictures.
This is our galaxy and we are here.
And this is only a small part of the Universe.
Do you see how many galaxies are there?
Every this little dot is a galaxy, not a star but the entire galaxy.
The Universe is the same with us and without us. Our galaxy would neither notice nor feel our disappearance.
That is why humanity must urgently work on its “EGO”. The ego is the most dangerous thing a person can possess but if some people jumped from the height of their ego to the level of their intelligence it would be a deadly leap. 
So remember, confidence isn’t thinking you are better than everyone else, it’s realizing that you have no reason to compare yourself to anyone else.
This life is not a competition, it is a journey.
Much love
