I'm guided in the darkest night

I'm guided in the darkest night
By flashes of auroral light,
Which over dart thy eastern home
And teach me not in vain to roam.
Thy steady light on t'other side
Pales the sunset, makes day abide,
And after sunrise stays the dawn,
Forerunner of a brighter morn.

There is no being here to me
But staying here to be
When others laugh I am not glad,
When others cry I am not sad,
But be they grieved or be they merry
I'm supernumerary.
I am a miser without blame
Am conscience stricken without shame.
An idler am I without leisure,
A busy body without pleasure.
I did not think so bright a day
Would issue in so dark a night.
I did not think such sober play
Would leave me in so sad a plight,
And I should be most sorely spent
Where first I was most innocent.
I thought by loving all beside
To prove to you my love was wide,
And by the rites I soared above
To show you my peculiar love.
