“Perpetual quietness of heart. It is to have no trouble.
It is never to be fretted or vexed, irritable or sore;
to wonder at nothing that is done to me, to feel nothing
done against me. It is to be at rest when nobody praises
me, and when I am blamed or despised, it is to have a
blessed home in myself where I can go in and shut the
door and kneel to my Father in secret and be at peace,
as in a deep sea of calmness, when all around and about
is seeming trouble.”–Andrew Murray

This quote hangs near my desk at my work place. Many folks define humility in other ways but to me these few sentences distill what humility means to me. A perpetual quietness of heart. What practice would produce such a condition?
