A quiet heart...
"Unless the heart be kept peaceable, the life will not be happy.
If calm does not reign over that inner lake within the soul which
feeds the rivers of our life, the rivers themselves will always be
in storm. Our outward acts will always tell that they were born
in tempests, by being tempestuous themselves. We all desire to
lead a joyous life; the bright eye and the elastic foot are things
which each of us desire; to carry about a contented mind is
that to which most men are continually aspiring. Let us
remember that the only way to keep our life peaceful and
happy is to keep the heart at rest, for come poverty, come
wealth, come honor, come shame, come plenty, or come
scarcity, if the heart be quiet, there will be happiness
anywhere. But whatever the sunshine and the brightness, if
the heart be troubled, the whole life must be troubled too."
