No bird soars to high, if he soars with his own wings
A Robin Red breast in cage, puts all the heaven in a rage
A dove house filled with doves and pigeons
Shudder hell thro' all its regions
There was a time when birds, these mythical animal, live among us
Unfortunately, I have never known this period
When I was born, they had already all disappeared
Nothing soars too high, if I soar with my own wings
[William Blake/1757-1827 - an English poet, painter and print maker]
