And why within me does this strange light shine,

As the soft nightly moon through groves of sombre pine?

Fine essence of the opiate dew of sleep,

Dear extract of all subtle powers that kill,

Be mine the first-fruits of thy strength to reap!

I look on thee, and soothed is my heart’s pain;

I grasp thee, straight is lulled my racking brain,
