There is another most interesting side to this subject, and that is the spiritual development. A man who develops spiritually also shows the qualities of those spheres whence he has come, and of those substances on which he has lived. For instance the first quality that a spiritually advanced person shows is that he is more perceptive, more observant, more responsive, more outgoing, more appreciative, more sympathetic, more harmonious. Where does it all come from? It comes from the animal kingdom.
