“He that is strucken blind can not forget the precious treasure of his eyesight lost.”

Never Give All The Heart http://poetry.poetryx.com/poems/1545/
In The Seven Woods (1904)
Context: Never give all the heart, for love
Will hardly seem worth thinking of
To passionate women if it seem
Certain, and they never dream
That it fades out from kiss to kiss;
For everything that's lovely is
but a brief, dreamy, kind of delight.
O never give the heart outright,
For they, for all smooth lips can say,
Have given their hearts up to the play.
And who could play it well enough
If deaf and dumb and blind with love?
He that made this knows all the cost,
For he gave all his heart and lost.

Chorus 6
An die Freude (Ode to Joy; or Hymn to Joy) (1785)
Context: Sense of wrongs forget to treasure—
Brethren, live in perfect love!
In the starry realms above,
God will mete as we may measure.

Bodhicaryavatara
Context: Like a blind man fumbling in garbage
Happens to find a rare and precious gem,
Likewise I have discovered
The jewel of the precious Bodhimind.
Thus was found this supreme ambrosia to dispel
The Lord of death, destroyer of life;
An inexhaustible treasure able to cure
The poverty of all sentient beings.
