Famous quotes containing the word pulse:
“She needs no man,
herself
is that dart and pulse of the male,
hands, feet, thighs,
herself perfect.”
—Hilda Doolittle (1886–1961)

—Ralph Waldo Emerson (1803–1882)
“I know you not, this room never,
the swollen dress I wear,
nor the anonymous spoons that free me,
nor this calendar nor the pulse we pare and cover.”
—Anne Sexton (1928–1974)
