What is the symbolism in the following comment, which is a paraphrase from Act II, scene i by the Lambs of Duke Senior's speech in As You Like...

This quote is part of a href="http://www.bartleby.com/1012/5.html">paraphrase written in 1878 of
Duke Senior's speech in As You Like It about his living conditions
in the forest of Arden, Act II, scene i. "These chilling winds that blow" literally
refer to winter winds blowing on one who, like Duke Senior, lives mostly out in the
open. Symbolically these bone chilling winter winds represent the sorrows and troubles
that beset all humankind at one time or another and in one form or another. This
symbolism is reinforced by the phrase "blow upon my body," which is literally the
physical body and symbolically the representation of the psychological self that suffers
from adversities.

The point being made is that these cold
winds, these troubles, sorrows, and adversities are the stuff by which our inner
qualities are revealed: "they represent truly to me my condition." Adversities bring out
a person's inner qualities that either rage against suffering in arrogant anger; or moan
and weep before trouble feeling they are too good to deserve hardship; or laugh
suffering off as unimportant and valueless; or with courage seek to find the best way to
solve and endure suffering.

The paraphrase of Duke Senior's
speech ends by personifying the cold wind by giving it an animal's bite and tooth: "they
bite sharply." The explanation for thinking of "chilling winds [of adversity] that blow"
as "true counsellors" is that though they are hard to go through and endure, they are
nonetheless not so horrible as the cold bite of "unkindness and ingratitude." This
alludes to Duke Frederick's usurpation of Duke Senior's kingdom and throne. Actually,
the paraphrase diverges here from Duke Senior's actual speech for he doesn’t allude to
Duke Frederick’s unkindness and ingratitude.  What he says is that the winter wind is
like "a precious jewel" because in Arden, away from court life ("exempt from public
haunt"), he finds friends, literature, religion, and all good things;
he:

Finds
tongues in trees, books in the running brooks,
Sermons in stones and good in
every thing.
I would not change
it.
