Or heaven's blue vault, is suffered to put forth
Of impulse or allurement, for the Soul
To quit the beaten track of life, and soar
Far as she finds a yielding element
In past or future; far as she can go
Through time or space—if neither in the one,
Nor in the other region, nor in aught
That Fancy, dreaming o'er the map of things,
Hath placed beyond these penetrable bounds,
Words of assurance can be heard; if nowhere
