What is channel?

Famous quotes containing the word channel:

    There may sometimes be ungenerous attempts to keep a young man down; and they will succeed too, if he allows his mind to be diverted from its true channel to brood over the attempted injury. Cast about, and see if this feeling has not injured every person you have ever known to fall into it.
    Abraham Lincoln (1809–1865)

    For, rightly, every man is a channel through which heaven floweth, and, whilst I fancied I was criticising him, I was censuring or rather terminating my own soul.
    Ralph Waldo Emerson (1803–1882)

    How old the world is! I walk between two eternities.... What is my fleeting existence in comparison with that decaying rock, that valley digging its channel ever deeper, that forest that is tottering and those great masses above my head about to fall? I see the marble of tombs crumbling into dust; and yet I don’t want to die!
    Denis Diderot (1713–1784)
