Gentleness which is taught morally is a different thing, but even gentleness in action and movement is also necessary. In every movement one makes, in every step one takes there must be rhythm. For instance you will find many examples if you look for them of the awkward movements people make; they can never keep well because their rhythm is not right; and that is why illness continues. It may be that no illness can be traced in these people, and yet the very fact of their movements not being in rhythm will keep them out of order. Regularity in habits, in action, in repose, in eating, in drinking, in sitting, in walking, in everything, gives one that rhythm which is necessary and which completes the music of life.
