Pure Heart
O heart, lose not thy nature.
^Hamlet,
Act III, Scene ii

I hold you as a thing ensky’d and sainted.
–Measure for Measure,
Act I, Scene iv

For such as I am all true lovers are,
Unstaid and skittish in all motions else,
Save in the constant image of the creature
That is beloved.
–Twelfth Night,
Act II, Scene iv

And the like tender of our love we make,
To rest without a spot for evermore.
–King John,
Act V, Scene vii
