Book III, 96: On our Meditation upon God

When thy ambitious knowledge would attempt
So high a Taske as God, she must exempt
All carnall sense; Thy Reason must release
Her pow'r; Thy Fancy must be bound toth' peace;
Thy Spirits must be rapt; They must exile
Thy flesh, and keepe a Sabbath for a while;
Thou must forget thy selfe, and take strong Bands
Of thy owne Thoughts, and shake eternall hands
With thy rebellious Lusts; discard and cleare
Thy heart of all Idea's; Then, with Feare,
And holy Reverence, thou must thinke of One,
As though he were not to be thought upon:
Conceive a Spirituall, a most perfect Beeing,
Pure, simple; At the selfe-same instant, seeing
Things Present, Past, and Future; One, whose Might,
Whose Wisedome, Iustice, Mercy, (in a height
Above Exceeding) is Himselfe, being Great
Without a Quantity, and most Compleat
Without Degrees; Eternall without space
Of time: At all times Present, without Place:
Think thus: And whē thy thoughts can sore no higher,
Stay there, Stand humbly silent, and admire.
