Analysis of I Am Going to Sleep

Teeth of flowers, hairnet of dew,
hands of herbs, you, perfect wet nurse,
prepare the earthly sheets for me
and the down quilt of weeded moss.

I am going to sleep, my nurse, put me to bed.
Set a lamp at my headboard;
a constellation; whatever you like;
all are good: lower it a bit.

Leave me alone: you hear the buds breaking through . . .
a celestial foot rocks you from above
and a bird traces a pattern for you

so you'll forget . . . Thank you. Oh, one request:
if he telephones again
tell him not to keep trying for I have left . . .
