By standing up and walking a step or two he makes his pulsation regular and puts his circulation in order, thus making himself psychically and morally ready to defend himself if the one who is coming should happen to be a foe, and ready to meet him harmoniously and on the same level, physically, mentally, and morally, if he happens to be a friend. Bending the head in a bow quickens not only the circulation in the head but also the magnetic current in it, for the head is the chief moral and spiritual factor in man. You will always find that a person with a tendency to bow is thoughtful, and it often happens that the one who keeps his head erect and avoids bowing is foolish. Man's life depends upon rhythm, rhythm in his breath, in the pulsation, in the beats of the heart and head, and it is irregularity of the rhythm of his heart or of his pulse that shows disorder in his health. It is regularity of rhythm that keeps man in a fit stage to go on through life.
