The two arms are the two directions of magnetic power, positive and negative, and in the breast is the center of these two powers. And the custom is that they embrace twice, distinctly on the right and left sides. This is also the exchange of Prana, the very life, the center of which is in the breast. There is a custom in Persia and in India that when a younger person greets an older one he bows his head, bringing it closer to his breast, and the elder person, taking his arms, raises him up, as if the younger person wanted from the elder person, love, light and life, and the elder person gives it to him and raises him with it. It also suggests a sentiment of modesty and humility on the part of the one, and help and encouragement on the part of the other.
