Shall calmly yield it to the arms of rest,
But which, or comes or flies, only at thy command!
Yet if when sleep the body chains
In sweet oblivion of its pains,
Thou bid'st imagination active wake,
Oh, Morpheus! banish from my bed
Each form of grief, each form of dread,
And all that can the soul with horror shake:
Let not the ghastly fiends admission find,
Which conscience forms to haunt the guilty mind—
