We see the world through
the lens of our beliefs!
As you look to this photo so imagine this, each one of us sees and perceives the world through a different lens and this is why for example a situation which is stressful for someone is not at all for another one.
Our mind is like a projector and shows us the external world through the lens of our beliefs.
This means that if we change our belief system, we then change our Lens and thus we see and perceive the world differently.
