An Analogy for Understanding
To understand this notion, consider a sheep that has all its organs insides emptied, and only its skin is remaining. All those internal organizations, when it was alive (meaning its flesh, bones, blood and vessels), are all consumed and have spiritually promoted. However, if you inflate the remaining skin, you will see that it has the same frame as the sheep, its shape, and mold. This notion is a practice in natural sciences to preserve animals and birds, often called “taxidermy” or stuffing the skin with chaff. To do this, they will first empty the internal organs and maintain only the fell, then stuff it with chaff or other substances. The appearance of the animal resembles a living one; only it lacks the movement of a living being.
