Do not be surprised by the fact that even an individual person, through his or her deeds, can cause an elevation or degradation of the whole world. This is an unalterable law that the whole and its parts are as identical as two drops of water. Everything that occurs in the whole occurs in its parts as well, and vice verse. Furthermore, whatever happens in the parts happens in the whole, because the whole is only revealed through the manifestation of its individual parts, according to both their measure and quality.
