Polygonal coffin of the limitations

Джамчо
You think that mind is all-powerful 
And able is to tame the flame
Which is raging in your blood -
But that's blood's very nature!
You can be whatever noble-faced,
Though "blue blood" is just speech's figure.
Wild horse is being tamed while running,
So what can I tell about tame of passion!
Give freedom to it - blazing
And fading away naturally -
There is aurora, so also there is set.
In cruel manner locked yourself into
Polygonal coffin of the limitations
You lose the point.
