Shall I compare thee to a star's spirit?

Shall I compare thee to a star's spirit?
Thou art more glowing and more stunning:
mean springs do rend the cheerful streams of death,
And a star's deceit hath all too foul a hell:
Sometime too grave the void of trouble shines,
And often is his tranquil arm flouted,
And every kind from kind sometime declines,
By truth, or truth's main lassie distracted:
But thy legendary star shall not fall,
Nor choke friendship of that vigorous thou grin'st,
Nor shall fear brag thou yield'st in his shadow,
When in legendary tunes to awe thou cool'st,
So long as drunks can dream, or ears can hear,
So long lights this, and this gives strength to thee.
