The bird represent the human soul.
The bar represent the human body and thoughts.
I feel that we all need to breathe the most clean air cause we risk to think too much and feel too less.
The air we need is out of the range of our own thouhts.
No thoughts means unexplored area for the mind and fear come to us so we get scared and we raise excuses...
This soul among billions has taken courage to take the quantum leap to the unknown.
