Famous quotes containing the word vigilant:
“You are the current of the frozen stream,
Shadow invisible, ambushed and vigilant flame.”
—Allen Tate (1899–1979)
“I am as vigilant as a cat to steal cream.”
—William Shakespeare (1564–1616)
“How vigilant we are! determined not to live by faith if we can avoid it; all the day long on the alert, at night we unwillingly say our prayers and commit ourselves to uncertainties. So thoroughly and sincerely are we compelled to live, reverencing our life, and denying the possibility of change. This is the only way, we say; but there are as many ways as there can be drawn radii from one centre. All change is a miracle to contemplate; but it is a miracle which is taking place every instant.”
—Henry David Thoreau (1817–1862)
