“Birds born in a cage think flying is an illness.”

“What is this thing called the existence? Is it all the things that we perceive it to be? Or is it something else? It's a gift. One of my favorite examples is the bird in the cage. You may think that you own the bird inside the cage, but you're wrong. You only own the cage. People think that they need to have a very fancy cage, that the more incredible the cage, the more incredible the bird will look. But the cage and the bird are really two different things. When the bird is gone, all that will be left is the cage.”

“Life is like a bird. Whose purpose of life is only to keep flying in the open sky. Do not imprison him in the cage of your misery because he suffocates and he torments day and night in the cage. Release him to fly in the open sky because he has the courage to touch the heights of the sky. Imprisoned in a cage, he loses his confidence and forgets to fly.”

“Ideas are free. But while the author confines them to his study, they are like birds in a cage, which none but he can have a right to let fly : for till he thinks proper to emancipate them, they are under his own dominion.”

“A cage went in search of a bird.”

“The caged bird sings with a fearful trill,
of things unknown, but longed for still,
and his tune is heard on the distant hill,
for the caged bird sings of freedom.”

“I am a cage, in search of a bird.”

“A forest bird never wants a cage.”

“God loved the birds and invented trees. Man loved the birds and invented cages.”

“How can the bird that is born for joy
Sit in a cage and sing?
How can a child, when fears annoy,
But droop his tender wing,
And forget his youthful spring?”
