If you want to enjoy freedom

Crows speak their own language - so they stay free.
But the Parrot speaks the language of others and becomes a life-long slave, and remains in a cage.

No one can ever remain free after abandoning their language and culture - their ideology and heritage.

Therefore, if you want to enjoy freedom - then never abandon your language, your culture, and your heritage.
Keep faith in yourself and never be ashamed of your ancestry, history, and cultural background.

Note: 

Language does not mean just the mother-tongue - 

it's also the beliefs - doctrines, and ideology.
