Book I, 25: On the Needle of a Sun-diall

Behold this needle; when the Arctick sone
Hath toucht it, how it trembles vp and downe;
Hunts for the Pole; and cannot be possest,
Of peace, untill it finde that poynt, that rest:
Such is the heart of Man; which, when it hath
Attayn'd the vertue of a lively faith,
It findes no rest on earth, makes no abode,
In any Object, but his heav'n, his God.
