We never know how high we are
  Till we are called to rise;
And then, if we are true to plan,
  Our statures touch the skies—

The Heroism we recite
  Would be a daily thing,
Did not ourselves the Cubits warp
  For fear to be a King—

My life closed twice before its close—
It yet remains to see
If Immortality unveil
A third event to me

So huge, so hopeless to conceive
As these that twice befell.
Parting is all we know of heaven,
And all we need of hell.

Poor, impious Soul! that fixes its high hopes
    In the dim distance, on a throne of clouds,
And from the morning's mist would make the ropes
    To draw it up amid acclaim of crowds—
Beware! That soaring path is lined with shrouds;
    And he who braves it, though of sturdy breath,
May meet, half way, the avalanche and death!

O poor young Soul!—whose year-devouring glance
    Fixes in ecstasy upon a star,
Whose feverish brilliance looks a part of earth,
    Yet quivers where the feet of angels are,
And seems the future crown in realms afar—
    Beware! A spark thou art, and dost but see
Thine own reflection in Eternity!

There is a faith that weakly dies 
When overcast by clouds of doubt, 
That like a blazing wisp of straw 
A vagrant breeze will flicker out. 

Be mine the faith whose living flame 
Shall pierce the clouds and banish night, 
Whose glow the hurricanes increase
To match the gleams of heaven’s night.
