'And whiles against a thorn thou bear'st thy part, (1136)
To keep thy sharp woes waking, wretched I, (1137)
To imitate thee well, against my heart (1138)
Will fix a sharp knife to affright mine eye; (1139)
Who, if it wink, shall thereon fall and die.
These means, as frets upon an instrument, (1141)
Shall tune our heart-strings to true languishment.
