Science knows that there are two types of feathers--the ones with the rachis (stem) in the center and the ones that have the rachis off center. The difference is that the off-center stems are only grown by the birds that can fly. In addition to the stem being off center, the individual barbules in the vanes are interlocking. This is why our last book in the series Going Towards the Nature Is Going Towards the Health is entitled Feather by Feather. The reader will now attain knowledge to overcome the challenges that lead towards disease and see the bigger picture in climbing to the highest stages of health--in other words, happiness. Because health is happiness. Shaman Melodie McBride
