What must one do in order to develop this faculty, to find out if one has this faculty in oneself? As a mechanism wants winding every day, or a musical instrument wants tuning, so every person, whatever be his life and occupation, wants tuning every day. And what is this tuning? This tuning is the harmonizing of every action of the mechanism of the body, the harmonizing of the pulsation, of the beating of the head and heart, of the circulation of the blood; and this can be done by the proper method of repose.
