Famous quotes containing the word key:
“At the last, tenderly,
From the walls of the powerful fortress’d house,
From the clasp of the knitted locks, from the keep of the well-closed doors,
Let me be wafted.
Let me glide noiselessly forth;
With the key of softness unlock the locks—with a whisper,
Set ope the doors O soul.”
—Walt Whitman (1819–1892)
“Experience has shown that the trade of the East is the key to national wealth and influence.”
